I have a 1941 Pontiac coupe. Does anyone know if leaf springs off of a 1940 Chevrolet coupe will fit my Pontiac? I know that many parts were interchangeable between Chevy, Pontiac, Buick for the early 40's and leafs for the Pontiac will fit multiple years. I have locate 1940 Chevy springs and need to know if they will fit.
don't know about the interchange, but Eaton Detroit Spring can make you just about anything you want.
According to the Hollander book I have only Pontiacs from 41 to 49 will fit It also says '39-40 will fit but you have to drill the center hole 1" forward. Also looks like springs from a '50 will fit but has 7 leaves instead of 8.
I had St. Louis Spring make me a set of stock springs for my 41 chevy coupe. they will make stock or lower them 3", which is what I got. ~250 bucks shipped I believe. Also found them in JC Whitney too.
The only things that are going to interchange are gl*** and body panels from the cowl back, and even there there can be minor differences. Until 1960 all the GM makes used their own ch***is with virtually no parts shared across makes. Even the 1959-1960 cars all have their own ch***is with some of them being a completely different design than the others.
I found out when starting work on my '37 Buick almost nothing is interchangable between the different year Buicks, even model to model in the same year share very few parts. It must have cost a fortune for them to retool every year. I think after the war the car manufacturers found out it was cheaper to carry over some parts from year to year and from model to model, at least in the same brand.
