When I got my 46, it had both sides in place, and in real good shape.
If I recall correctly, the exhaust was routed up through the driver side pan. That might be the only problem you might have with the 235, (the exhaust routing).
I didn't put them back in place when I replaced the engine, and split the manifold.
They're sitting on a shelf in the garage. I believe all of the brackets are still attached to the truck.
Don't want to get into a gray area here, but I might be open to an offer, if you were to send one my way via a PM/e-mail.
