Trying to locate an original exhaust heat riser tube for 1972 Supreme with 350. Should have holes on bottom which are inline/across from each other to fasten together with mating bracket on passenger side exhaust manifold bracket using a pin, other end of tube connects with air cleaner snorkel. I am also in need of the connecting pin, a decent picture of a connecting pin, or any input on what pin is being used for restorations would be appreciated.

Dan - The "connecting pin" is just a long cotter pin. I'll try to find an example here and post a pic and/or a measurement. Basically, the cotter pin needs to be long enough to pass through everything and leave enough room on the other end to bend the cotter pin ends SLIGHTLY (the factory didn't bend the pin ends all the way flat, etc).

 

Factory original tube/bend/pin (Low mile unrestored '72 455). Your heat stove/shield will look different on a 350:
