256  Camaro Research Group Discussion / Decoding/Numbers / Re: Check out this Trim Tag on: June 26, 2013, 12:13:16 AM

Are you sure they haven't been replaced.

We are not discussing Z28's, but X77 never had gills / style triim and X33 includes those.

Hard to be 100% positive, since I haven't owned it since new, but all seams, welds, and landmarks seem to be 100% factory. Interior inspection of the quarters shows no signs of welded or bondoed holes in the louver areas. The other side - this car was a vinyl top car, so I now have the question as to whether it is an X66, or maybe an X22 Style Trim car. No paperwork with the car, just a 550 lb. P-O-P, black rear cove, SS trim, and N66 wheels. I have read the tables and info about quarter trim on non-X22 SS cars, and also have heard of some of the early COPO cars being X66 cars - I haven't seen all COPO's with quarter trim, either.
My only reason for discussing an X77 vs. X33's was in relation to the Style Trim availability, which I tied to X66/X22 vehicles. Sorry to digress during an open discussion.

X66 is not style trim equipped, so it shouldn't have wheel well moldings, but would have the quarter gills.

Are you sure ? My non-X code (12A) X66 was never drilled for the gills, best way to differentiate between an X22 and an X66 early car IMO (where you lack any paper documentation). My X77 is the same way - no piercings in the quarters, and no gills ever -

258  Camaro Research Group Discussion / Originality / Re: z28 with white stripes, cowl pics on early 69 cars on: June 23, 2013, 05:40:43 PM
Had to be the cowl white first - the firewall line is feathered up to the top edge of the firewall, black over the white. Mine looks like white, body color (LeMans blue), black firewall paint in that order. If anything is different, it could be BC first, then white - awfully hard to tell. Maybe this pic sheds a little light on it -

As with any GM product, there were probably more than one supplier even on small parts like water necks. Note the two flange marked castings attached - two different fonts, two directions to the numbers (one in, one out). I have heard before that the Corvette restorers prefer one over the other - which is which ? Got to have date implications -

I forgot to add that my 01C X77 has it on the neck - same outlet since I bought the car in '73. Can't say yes or no if it was replaced before '73, but I worked on the car in '72 - same everything when I bought it a year later.

261  Camaro Research Group Discussion / Decoding/Numbers / Re: another trim tag real or fake on: June 21, 2013, 05:43:20 PM
Looks good to me - good swipe of paint remover will do wonders. Tag is pretty straight, rivets look original IMO.

262  Camaro Research Group Discussion / Maintenance / Re: Is this tear is vent window rubber fixable? on: June 20, 2013, 09:45:22 PM
A dab of 3M Weatherstrip Adhesive (black) should hold it together - that stuff sticks to anything, great bond when it cures out. I patched my door window weatherstrip on the Z11 (top corner of windshield when it dry rotted and fell off, still there after 10 years or better.

Aw, shucks - I'd hoped it was for real and would drive the value of mine up along with it when it sold for $91K.

One more note - doesn't it drive you crazy when someone spends so much time (and money) "restoring" a car, spends a lot on pictures, composing the ad, and sharing all kinds of catchy statements, and still won't take the time to use a spellchecker or a dictionary ?

265  Camaro Research Group Discussion / Originality / Re: Another ebay 69 with fake tag on: June 13, 2013, 10:48:20 PM
Wonder what it was originally?

Could be anything. One thing for sure - my 12A X66 car does not have the X66 on the tag - I believe this tag is a week early for one, for two it's just too perfect. IMO -

266  Camaro Research Group Discussion / Decoding/Numbers / Re: '69 350/300 hp block number ID... on: June 12, 2013, 09:02:30 PM

Engine casting # is:  8956618. I know there were a few casting #'s used for 69 350's, is this one correct for 350?

I'm trying to make sure that this is not a "DZ" motor, because even though that would be a good find, would not be correct for his '69 pace car (w/ small block).
 

One other block to look for, which appears in a lot of Z11's (like mine), is the "388" block, also marked HA or HB for the suffix code (manual or automatic 300HP 350's) - I have also heard, but haven't personally witnessed it, that there were a very few DZ motors produced with this casting during a shortage or changeover to the next casting number. The 388's also used either "041" or "186" 1.94/1.50 valved 300 horse heads, just the same as 6618's and the eventual 010 blocks. My Z11 is an 03C car, BTW.

My original is lined, as are the 4 examples of NOS adjustable masts in the pics that follow. 3 are '69's, 1 is a '68, and the 5th mast (at the top, barely visible) is an NOS AM/FM. The '68 mast is exactly .375" shorter in overall length, plus the mount is threaded rather than a splined fit.

These are/were in original GM packaging purchased from GM dealers - 100% positive they are NOS GM.

'69's are 19.375 OAL, '68 is 19.00" OAL. AM/FM fixed mast is 31.500 OAL.

Regards,
Steve
268  Camaro Research Group Discussion / Originality / Re: AM/FM antenna mast height on: June 12, 2013, 08:33:24 PM
My NOS AM/FM fixed mast is 31.5" overall length, umounted. Part is in the original GM sleeve, so I know it's correct and original. If you need any additional dimensions, ask.

Steve

Is the pebble effect found in the metal or the paint?

The paint.

A couple of other things that might be a factor as well - considering wear in the pressure casting dies, which manifests itself in details that deteriorate over time (heat cracks, wear, rebuilding and replacement of die segments, updates and part number changes), plus in this case, paint processes that might vary batch to batch. I bought a pair of valve covers (aluminum finned LT1/Z's) under the intermediate part number back in the 80's - the die damage (heat cracks) were really visible under the polishing around the edges - sure enough, there was a part number change shortly after I bought mine, and Presto !, heat cracks disappeared, fresh, smooth castings were on the market again. I think when GM contractors got to the end of a production run, they squeezed processes and dies to the limit to keep from having to spend money to renovate a dead-end process order. Just my opinion -

Steve
