RPO-NC8 Hardware. Need help please.
 

Anybody have a good pic of what the hardware looks like for this exhaust? Been looking at the 69 A.I.M. for installation, and I'm a bit confused on what the screws look like for the hangers and clamps...no dimensions stated. If I can just see them I can go from there. Near as I can tell I need these numbers, 9431541, 9411890, and 3922549 indicated in the A.I.M. RPO-NC8 A1-A3 pages 391, 2, and 3. I'm thinking at least two of those numbers can't be had from AMK or am I mistaken? The pic is what I have now.

Also, the extension, and the packing for the exhaust pipe will most likely be sourced from a muffler shop, correct? #3767555 and 556. These numbers I'm not sure if for BB or SB. I need for SB though.

Does anyone use the sealer-grease .50 oz that is indicated?

Thanks G.

I believe you have listed some of these incorrectly.

943151 should be 9431541
911890 should be 9411890

These have other non-exhaust applications. Someone may be able to get a pic.

Thanks William. Yeah, I have a '4' that needs slamming every once in a while. I fixed the part numbers. 3922549 I'm thinking those 2 black ones are for the over the axle muffler bracket. AIM says two ea for the standard system hangers, and one ea for the chambered hangers. And the zinc colored ones are for the hangers attached to the frame rails for the tailpipes. Still...there is the round clamp #7, pg 391 in the AIM, item #6 , and tailpipe hanger #4, page 392, item #3. These two I'm unsure of what they look like if I need an alternative.

That grease is high temp clear silicone. Here’s a pic of my nova hardware.

What are those inserts for John?

Well nuts. They go into the rear of the floor board. 69 Nova has 3 for each hangar. Camaro has 2. If your car has Factory dual exhaust they are already in place. If not there are dimples there and you drill them out and put in the special nuts. Just so happens my amk package came with them. But the car has them installed from the factory.

Yeah, I have the standard system hanging now getting ready to pull it out. Trying to get the hardware sorted out to install the chambered system this fall maybe.

RIV NUT = Steel or Other metal clinched threaded inserts. (Console & Exhaust)
WELL NUT = Rubber encased Nut (Radiator or Voltage Reg)

Hope this helps others. Did a little digging this A.M. and found something that looks to be close. (From research off T.C.) Looks like too much hardware for chambered system though. It's amazing the brackets that bolt up to the floor bottom only require one bolt. Now I just have to figure out where that bolt goes. The AIM is unclear, at least seeing it on paper.

Bolt goes through one of the metal brackets in the middle of your photo then through the over axle strap and into the floor pan - - orient the metal re-enforcement with the TAB pointed towards the floor boards (UP) The TAB acts as interference against the floor pan so you do not over tighten the strap -
