None present on my 1988.

it seems these parts help keep fasteners tight when heat/cool cycles
happen. Thank you Dennis!  I had no idea what purpose they served.

Archives suggest they're NLA. I guess by now, people aren't using them

Have people found any issues (fasteners coming loose?) using just
bolts, washers, nuts, at union between manifold outlet and J-pipe
inlet?

Also.... the "copper" nuts people refer to in exhaust installations.
Are these the Cadmium (I think) plated stover nuts? (slightly ovaled
lock nuts)

Much thanks,

Neil.
