What year trucks came with these and what do they look like?
I am about to pull the small block out of my original condition truck in favor of a big block.

I believe they came on all small block Mopars, 273, 318, 340, & 360 throughout their production. They were utilized on slat sixes, as well

They look like they'd be easy to make on a lathe. Let me know if you strike out.

I’m not near my truck to look, do these go on the bolts that bolt the manifold to the head?

Have you checked with R/T specialties? They stock hundreds of different small hardware pieces and fasteners for mopars. They even had the pierce nuts that they used to fasten body panels like are found under the trans tunnel cover.

Correct, they are utilized with the exhaust manifold attaching bolts.

Yes, there are aftermarket sources for them. There about $3.25ea. I only need two, so the price of the part is not the issue. The $20 shipping & handling is. I thought if someone had a pair they could drop them in an envelope and mail them to me. I've done that a number of times to help others out.

I just checked all 3 of the small blocks that I have. Apparently these were not used on poly 318’s And the manifolds were already gone on the la motor.
Maybe try a local pick and pull.
