Slant six manifold(s) mounting hardware

Seems like I just recently saw a sale post for manifold hardware & now I cant find it. Im trying to reassemble the slant in my 73 Duster. It came to me with a massive exhaust leak and running rough. It was assembled with nice shiny stainless hardware and stacks of washers. Id really like to use the proper spacers, washers and nuts if someone has any to sell.

Thank you,
Jay
