The documentation is going to take some reading and flipping in the '32 catalog! Tnk and hardware are listed out back in the truck section. I think we are talking B-82 and B-76 application, closed and open pickup. Long and short bolts tank to floor sills are listed there with nuts and stuff, numbers to get sizes decode in the back of book. There are other bolts listed as commercial chassis, tank to support...I think this means bare running chassis with no floor available so irrelevant here.
Need more reading and checkout of the big '32 book, which isn't here. As with many things, that actual '32 catalog gets very cryptic and can use expert elucidation! My '32 pickup has a '33 cab and non-stock rear tank so no direct experience.
