1  Camaro Research Group Discussion / Originality / Re: 1100837 Alternator Stamping - Original? on: December 05, 2013, 08:45:52 AM
Here is my 2 cents worth. Picture below is mine and OK'd by Jerry MacNeish. I talked to John Pirkle (Now Deceased) on the stampings
of alternators and he indicated that a lot where slopy stamped. Many had that "ghost" figure we see all the time. Stamping of the alt.
where not in the same ballpark as engine stampings. (Where some where stamped on the slopy side also) I think most org. are trying to
make a science out of this from a time where no one cared how the stamp was including the stamper. IMHO Larry

Being a Corvette guy also; have gone to many Al Grenning/John Hinckley seminairs. IIRC the painting process changed in 1968. Prior
to that there was some overspray on the exhaust manifolds but none on them from 1968 on up. Correct me if I am wrong. Larry

With my Chevrolet products I use the paint from "Quanta Products". Have passed in all judging
like NCRS/AACA. http://www.gastanks.com/Restoration-Spray-Paints/products/1954/
Thanks--Larry

Interesting that the Zone Letter refers to discontinuation of NC8 dual chambered exhaust for "Camaro SS". If that included Z28, perhaps it was a typo and meant to be "Camaros" ??

Another question comes about is what happened to all the Chamber Pipes and Hardware that where left in the production line bins at the time of                                         May 19? I think we can all assume that the supply of the Chamber Pipes and Hardware didn't run out on May 19th. Would not GM want to use up
the supplies then change it plans like they do with all there other change over parts?? Larry

Can you guys tell me if an O1C build date Z/28 would of came factory with Chambered Exhaust? Thanks!

FWI: The last entry on the NC8 option in tha AIM is 6/13/69 indicating the RPO is cancelled. Larry

Remember that the dates in the revision block in the A.I.M. are only the date the sheet was revised in the Drafting Room, not the date the revision occurred in production; NC8 was cancelled on May 19th.

What GM documantation backs up your(or anybody elses) exact date of May 19th?? Just curious. Larry

your car itself may be 1/2" lower on the driver side....  it's not uncommon after years of having a single passenger (the driver).. Smiley

69Z28: Thanks for the response. Never thought of that; where would be a good accurate place to take that measurment on the car?
Thanks--Larry

Just a followup with a question. Everything installed nicely. Looks/Sounds great. On observation looking at the muffler from the rear of car is looks very nice
and equal distance from the floor. (This is with the car on the floor; jackstands removed) But when I take a measurment with a ruler there is a 1/2" difference
from the floor. The driver side is closer to the floor then the passenger. The AIM does not give any specs on this. If anybody out there with a chamber pipe option
can you measure yours? Is mine within the limits? When I installed the new hanger on the driverside I used a floorjack to raise the system up. Comments Please!
Thanks in advance--Larry

Steve: Thanks Much. Larry
10  Camaro Research Group Discussion / Originality / Chambered Pipe Vs. Regular Muffler Bracket hole for 1969 Z28? on: July 12, 2013, 01:05:56 PM
Are the bolt holes(in the body) that holds the straps for the Chamber Pipe Muff. and the bolt holes for the regular muffler system in  the same identicle location? The location is
above the Transverse Muffler for both systems.  In both cases it holds staps(different) that bend downward and go behind the clamps on both systems. I hope I am
eplaining this correctly. Thanks-Larry
11  Camaro Research Group Discussion / Originality / Re: Looking for Driver Side Back Chamber Pipe Hanger #3965182;Any Idea's? on: July 07, 2013, 06:47:05 AM
Just a followup; it does not have to be a NOS one; reproduction will do fine as this hanger is very hard to see. Larry
Any help?? P.S. Ebay item#150609932920 has a picture of them. (Center Right in the Picture)
12  Camaro Research Group Discussion / Originality / Looking for Driver Side Back Chamber Pipe Hanger #3965182;Any Idea's? on: July 06, 2013, 12:06:58 PM
Upon changing my chamber pipe back muffler I discovered one of the hangers (3965182) was broken. Any
idea's where to find one? Don't really (unless I have to) want to buy all the hangers as a set as all mine are
fine. Help! Anybody!
13  Camaro Research Group Discussion / Originality / Re: Need help/advice on changing exhaust systems on my 69 Z28. on: July 02, 2013, 05:57:31 PM
Are you referring to the chambered cross mufflers?   Allens does make the chambered system as well as regular systems for all kinds of collector cars...

69Z28-RS: Yes the Chambered Cross Mufflers-All my other pipes(Exhaust-Front Muffs-Tail) where all fine. My car is a "trailer queen" so
engine is not run long so the cross muffs rusted out from the inside-out. So I have part aluminum and part S/S system which Allens indicated
no problem. Sounds a lot better now. Larry
14  Camaro Research Group Discussion / Originality / Re: Need help/advice on changing exhaust systems on my 69 Z28. on: July 02, 2013, 02:06:34 PM
Just a follow up. I got Allens Exhaust to make me up the two back mufflers (Cross Muffs.) in stainless steel and
told them to try to make them less noisy then normal. He did just that and they fit like a glove and sound real
nice. Should be set for a long time now since they are S/S. Thanks for the comments. Larry
15  Camaro Research Group Discussion / General Discussion / Re: Original Yenko Camaro Warrenty? on: July 01, 2013, 07:18:13 AM
Found the answer to my own question. Was at the AACA Grand National this W/E and the class I was in was just awsome. Yenko's-Z16-L72 Bascaynes
and a lot more anyway here is the story:

 Talked to the Yenko owners in my class(36B) at Moline this weekend and as I understand it is that the 69 Camaro
 Yenko's where actually COPO cars ordered from Chevy so the engines where installed at the factory so the GM warrenty was like any other GM car. When
 the car arrived at Yenko Dealership he put on the strips an all the emblems, wheels and etc. It was a different story though for the 67 and 68's as he did
 R/R the engines and the warrenty was put out by him not GM. Thanks-Larry
