Make sure they Save the TAG!

Better yet, remove the tag before you send it out !

Alan Colvin's Chevrolet by the Numbers supports it. I have seen both on L48 69's.

Gary,

Good coverage in the 1969 Chassis Service Manual starting in section 12-35 for the procedures if you want to tackle this yourself. I would not recommend disassembly of the gearcase unless you want to bolt it back together - the factory procedure is to drill out the staking tabs and bolt it back together using "screws, nuts and washers.....contained in a service repair package". If the gears are O.K., I recommend replacing the brushes, cleaning the armature, outer cases, replacing the mount cushions: paint and detail and you should have a pretty good looking and functional part. I have only seen one business advertised in Hemmings in a good while for restoring electrical wiper motors - might be more options on the net, but I have no reference for you. Parts might be tough - if you have a friendly dealership, if they don't list them as current have them look them up on the locator - you might get lucky. You can also try a local AC/Delco service parts company if there are any left around - I haven't had the occasion to buy from one in a couple of years.
Please see the following - these are the only details I have ever seen different between the original part # 5045605 RS wiper motors assemblies, and replacement motors like the # 4918442. The end frame (rear bearing support) cover is stamped with the part number, there usually is a sliver tag with part number and date code as you see in the pic (now available as a repop, correct), and the 2 drilled holes for the directional valve (solenoid coil operated) mounted directly on top of the motor housing, as you know. The valve and valve parts are produced by Impala Bob's that I have seen - he apparently is the primary supplier to a lot of the catalog houses, but will sell components if you can make repairs to your original. The valves are pretty fragile, and break easily when old.I can supply you with part numbers if you don't have access to a GM parts manual - tell me what you need.

Regards,
Steve

  As for the doubters I feel like others have said. I know that my 68 is a Z/28 and not a clone or whatever term someone wants to use; and if the doubters don't believe it then too bad because I bought it for me to enjoy not to convince someone else of what it is.

Amen

Steve,
Are you going to the swap meet in Nashville on the 18-19th?
Gary

Gary,

Hopefully. I'm usually at the Stones River AACA swap meet in Feb as well. I enjoy these meets - I have bought a lot of great parts at both over the years. They are the ray of sunshine in the bleak winter months -

Steve
366  Camaro Research Group Discussion / General Discussion / Re: 1969 NOS ZL-1 engine possibility ? on: January 10, 2013, 11:06:50 PM
I checked my '74 parts manual before I posted the pictures - the partial or fitted 427 blocks are different part numbers. This probably appears in the Special Performance parts listings (I have one around here somewhere), which would support the part number on the tag. I do not have a clear picture of the freeze plugs. I do have a pic of the 842 head (838 part number), plus the other service part head. So far, everything appears as he described it - early 70's. No claim that it is a '69, just a ZL-1 block. Or should we call it an L88 ? One in the same ?

Just my opinion -

Regards,
Steve

I've had my first Camaro since '73. I hate fakes, but I don't mind clones too much, as long as someone doesn't try to pass them off as legit. In any event, my Camaros have increased in value every year, and I take absolute pride in owning them. Like Mike, I hope to pass them down to my kids as a legacy and an inheritance, and I hope that I can do that without having to part with any of the cars to afford their continuing educations. BTW, my first '69 Z, the '73 purchase, has been on hold since the birth of my first child - your responsibilities change, but your dreams don't.
 
This hobby is total therapy to me - I enjoy scrounging for parts, attending swap meets and shows, talking to my friends and fellow owners about them. They are a link to our past, a time when things were very different and life seemed a great deal less complicated than it has become today.

Keep the faith - and keep your car.

Regards,
Steve

Guys,

Please forgive the pictures-of-pictures - it's the only way I could figure out how to reduce the file size (pics are about 4+ MB apiece). I didn't thiink this was a '69 casting date block, as the owner said all along that he bought it in '73 new, but I had always heard (at least) the correct early casting code was an 053. Please note the Special Parts notice , with part number on the tag, plus the date. This tag is apparently right on the crate itself.

Alan Colvin stated in the C-b-t-N's that the 052 was the L88/ZL-1 block, but also mentioned that the 053 was reported (unverified) to have been installed in the first of the ZL-1's. Whether this is a service block, or a Can Am part, or one of the last of the initial casting runs through the Winter Foundry, it's certainly unique and a real surprise to see such a rare part literally in my backyard. I do also agree with Oaklyss on the 074 heads - Colvin does substantiate this, although I always thought them to be '70 and up -

Regards,
Steve

Gary,

   Thanks for the pics - tremendous resolution but the files are indeed huge. Certainly an 053 casting, love the shot of the crate and the tags (particularly the "off-road use" tag. How in the world could someone keep this bottled up for 40 years and not build it - I don't have the answer.

   One head appears to be the service casting number, one is definitely an 842 - both are absolutely new appearing/bare. I do see what appears to be some surface rust areas in the block sleeves, but nothing too serious. I wouldn't kick it out of the garage for being naked -

Regards,
Steve

Gary,

I'm about 30 miles from M'boro - I'll be glad to follow up for anyone on this too. I'm through there about twice a week as it is (including tomorrow).

If it's not too much trouble, I'll send my email by PM if you will forward me copies of the pics. I'd like to see it -

Steve
371  Camaro Research Group Discussion / General Discussion / Re: beware of the look alike 68-Z28 fan on: January 08, 2013, 09:47:21 PM
I'm saying all the centers were stamped from one machine and then they would run batches of correctly machined specs for a particular fan. This again could be the correct fan in all aspects except the original configuration of the bolt holes.

I agree completely. I have a lo-po 3.00 fan here, and it's identical to the 3.25 fan (also Jerry references the similarities between the two), with the exception of the bolt circle. Same rivits, center, markings and the clutch even looks the same, except for the bolt circle. I also agree with Kurt, "it sure sounds like it has" -

Regards,
Steve

Ed,

    Thanks for moving it - I should have thought about the VIN before I posted it.

    Here's a twist - I mentioned this to a customer today; turns out he knows the owner (both are SS or SS/E racers), and swears that it is a legitimate ZL-1 motor he has been prompting the owner for years to sell. I would jump at the chance to verify the thing - it would be worth a dollar or two (to say the least) to a ZL-1 owner if it actually was a dated NOS block/heads combo, and not a recent GM recast. In replacement terms, one might consider it to be an orphan -

Regards,
Steve
373  Camaro Research Group Discussion / General Discussion / Re: beware of the look alike 68-Z28 fan on: January 08, 2013, 11:07:39 AM
Zoom on the front side of the fan, you can plainly see where the original 3.00" circle bolt holes have been welded up, and the pattern indexed and redrilled at 3.250", which is the correct bolt hole circle for the L78/Z28 fan blades. All other markings and the rivet count appear the same between the applications. I've seen "H" and "W" markings appear on both low po and hi po blades, 4 rivets/blade. Gotta hand it to them for innovation -

Regards,
Steve

Anyone posted this one yet ? Seems unlikely, or could be the recast block/heads - if I had $38K to spare, I'd call -

Imagine what didn't get saved.


Now, add those to what has gone on to the Great Beyond Bone Yards in the Sky and really get depressed -
