Normally, we do not post notices here for our Swap Meet posts.
However, be sure to state the truck you will be putting the 235 exhaust manifold into. The angle of the "down pipe" changed at some point. Also, maybe someone will post info here on whether the 216 exhaust manifold will work for you.
The angle of the later 235 (and any 261) exhaust manifold might work OK in an earlier truck, unless you want it to easily line-up with an existing exhaust line.
