Originality / Big Block Distributor Hold Down Clamp

« on: July 17, 2013, 02:06:19 AM »

Which hold down clamp is correct for a '68 396/325? The wire type or the plate type?

Thanks,

Bob

Ed,

Excellent. Thank you very much.

Some where in the previous ownership of my car the service replacement cover and bolt on timing tab was installed. Today I just scored a purchase of the 7" version with the timing tab welded on so all is well.

Thanks for providing the examples.

Did the timing chain cover for a '68 396/325 have the timing tab welded on the cover or did it use a two piece design (cover plus bolt-on tab)? I believe the two piece design was for replacement covers only but not 100% sure.


Thanks,

Research Topics & Reports / Re: Original 67-69 Camaro driveshafts - information requested about your car

« on: July 09, 2013, 04:52:21 PM »

John,

Yes. Needless to say, I was extremely surprised to see the pins when I pulled the driveshaft out during my restoration. I quickly began my search to try to figure out what was going on and ran across across this thread:

http://www.camaros.org/forum/index.php?topic=8333.0

Of course I can't say with 100% certainty that this is the original born-with driveshaft, but I can assure you that in my 35 years of owning this car the driveshaft has never been removed. The other thing that I found odd was that the date code (0207) on my rear axle tube is one week after the build date (01D) of the car. Again, I found this odd and from what my research has found, GM had a strike right around the time my car was built and may have resulted in some parts being delayed from their suppliers. I also found this issue on my brake booster which is date 038. Could some parts have been changed during previous ownership? Maybe, but from what I'm uncovering during my restoration there are a few more parts that seem out of sequence with the build date of the car. I'd be curious to know what others have found with cars built around this time frame.

Decoding/Numbers / Re: Shock Absorber Nut

« on: June 19, 2013, 10:36:27 PM »

Thought I would provide a quick follow-up posting to this thread with the hopes it may benefit someone else who went down the same path I did.

I ordered the superseded shock nut (p/n 3866766) mentioned earlier in the thread from the local Chevy dealer. The nut in the attached image is what I received today. It's pretty darn close to the nuts from some of the images posted from others. The thickness measures .371". It's difficult to tell but it does not appear to be zinc plated.

This is what I'm going to use which brings me a whole lot closer to what was originally used versus the nuts I picked up earlier.

Gary,

You're right! I was unaware that the Camaro Nationals had seperated from Carlisle.  That explains why the past couple of years I've noticed a dramatic decline in the number of Camaro's at Carlisle. I was going to take Friday off to go to Carlisle but now I may have rethink my plans.

Thanks for the info!

Ed,

I was referring to the GM Nationals at Carlisle next week. Always a bunch of great cars there to look at.

Many thanks to all for the replies.

Looks like zinc plating is the consensus. I think I'll run down to the local Chevy dealer on Monday and order a handful of the superseded part number and see what they look like. Hopefully it'll be a zinc plated nut without the bevel and dimensionally correct.

Thanks,

Bob

Thanks Mike. I think we're getting closer.

With what both you and Ed have found, it would appear that a "standard" 5/16" nut was used, albeit without the bevel.

I guess the only remaining question is whether or not this nut was cad plated or zinc plated.

Thanks,

Bob

Ed,

Very interesting!

So it looks like the nut is a "standard" thickness (5/16") nut but with no bevel.

I ran across this Grade 8 yellow zinc plated nut (yes, I know major overkill!) at Pep Boys last night. I realize that is not cad plated and in light of your recent post, has the bevel on it but it gets me a little bit closer in appearance to having the correct nut.

I suppose I could go to my local Chevy dealer and order the superseded nut, strip the plating and then have it cad plated. I was just hoping for an easier solution. 

Carlisle is only a week away so I'll have a look at some cars there to see what is being used.

Maybe other members could also chime in and post what is on their car.

Many thanks for all your help!

Thanks Ed. Yes, I did see that it was superseded but was not aware that it was cad plated.

Do you know if this nut is the short "jam" style nut (which measures  approx. .221 inches thick) or is it a standard nut (which measures approx. .323 inches thick)?

Thanks,

Bob

Decoding/Numbers / Shock Absorber Nut

« on: June 14, 2013, 05:00:58 PM »

I was just about ready to install my front spiral shocks and realized that I don't have the nut that attaches the top of the shock to the subframe. On page 61 of the '68 AIM, it lists this nut as part number 1365067. I looked in the AMK catalog and unfortunately they don't list it. I already have the grommets and retainers so all I need is the nut.

Does anyone know what the dimensions and finish are of this nut? Anything special about it?

Many thanks Mike and Chic! You've both been a great help. Very much appreciate it.

Time to buy some clips and some of the Palmetto concentrate and have some fun.

Chick, Thanks for the tip. I have couple more questions if you don't mind.

- I've attached a picture of one of the clips. My thought on re-installing it was to slight close the end of the clip that goes into the subframe and then use your center punch idea to open it back up once it's been installed. Since I haven't purchased any of the new clips, I don't know what the back side looks likes. Is it similar in design to the originals?

- In terms of phosphating, I'm considering using the Palmetto Enterprises concentrates. It looks like they offer both Zinc and Manganese. My question is, what color phosphate should the clips be? Charcoal black or light to medium gray?

Thanks!

Bob

Chick,
Perfect! Many thanks for confirming exactly what I thought. When I pulled my clips off they looked exactly like yours although it was difficult to tell after 45 years.  What threw me off was that all of repop suppliers only sell this clip in the red color (why, I don't know!).  I must admit that what got me thinking about this was one of the photos in your build (which by the way, has provided me with a ton of useful information) showed them as phosphate. From what both you and Mike have now confirmed I feel confident in applying a phosphate finish.

BTW...I have already beaded my originals and there is no sign of any pitting and they're in really great shape. Since they are original to the car and have the anchor markings I'd like to reuse them if possible. So, in your opinion can these be phosphated and reinstalled or would you suggest buying new ones and go through the process of beading and phosphating? Also, you're idea of using a center punch to reinstall them is great. I kept scratching my head trying to figure how these got installed to begin with.

Once again, many thanks!

Bob
