1939 Pontiac and Chevy simularities????

I am considering a 39 Pontiac tudor and got to wondering if anything transfers over to it from 1939 Chevy tudor engine swap kits such as Chassis Engineering? Same frame dimensions? Tophat style Chassis? Later year (49-60) Pontiacs + Chevy's are very simular and parts interchange. So I got to wondering about 1939 GM's B4 I get too serious about the Pontiac.

never mind I decided to pass on it. Too off the norm car w parts missing that are HARD to find = $$$$
