I have part of my originals still on my 10A car but it might not be better than these pix posted here. The rubbers have been replaced but the bracket on the car has never been off. The screws were too rusty to remove back in the 80's so I left the brackets on there. The rest of the rubber hangar was cut off and thrown in the trash as they were obviously "useless, and in the way" (I know, I know - OMG what was I thinkin!?!?). I do still have the original little black rubber moon shaped piece in a jar out in the garage.

I have some big screws that I saved that might be correct to hold the rectangular plates in place but I have never seen any others to know if they are correct or not.

Want pix?

-Mark.

My 9B L34's chambered exahust was replaced by the orig owner due to noise. When he replaced the system with a GM replacement tranverse system he reused the chambered hangers. Yes it did not fit real well because of the short over the axle hangers. This car is real early and used the strap type clamps on the over axlel hangers. If you look closely they were stamped 1 7/8. I have a used assembly line correct chambered for the car with NOS clamps, but before I install I want to remove the dealer under coat.

Steve,
I appreciate the photos, yours are the same as mine.

In addition you have cleared up the Question Eric had in reference to the Strap type clamps for the over the axle hangers.
Eric Gardner specifically asked if I had them, (I don't) as he wanted to know if they actually came production line installed, when I speak with him I will inform him as well as refer him to this thread.

Thanks again,
James

When I purchased the replacement chambered system from them in 1999, I spoke to Eric about the strap clamps. I believe at the time he had thought no cars came with them, although they were shown in the AIM (as we know the AIM is not perfect). Once I verified my car in fact had them he offered to reproduce them. My understanding is that they offer the strap style now.

They show the strap type for some GTO applications so I'm sure it would not be to much of an issue to substitute them.
In addition to the bolt, lock washer, nut for pipe attachment (which is correct) the arched rubber piece is the Big difference in the early rear clamps VS the later style.

Yes my understanding it was done to make it easier to install since you only had a bolt. Probably a cost savings benefit as well.

How about some NOS pix?  I grabbed these pix from an auction.  I could go out to the car and take snapshots of my originals but these are easy for me to post.

You guys are showing me (again) how I screwed up when I didn't buy the chambered pipe hangars back in the 70's when I purchased the chambered exhaust system parts from GM... and to top off how ignorant I was, I didn't know at the time that my 9C car couldn't have come with them....  we live and we learn!  :)

Do all the originals have the part number stamped in them? or was there different vendors and some were stamped and some weren't?
