Graefen Posted September 5, 2022 Report Share Posted September 5, 2022 I have a stock running P19 busines coupe and just purchased a '55 DeSoto running Hemi parts car. The plan should be obvious. Out with the '50 flat six and in with the '55 Hemi. Much improved brakes should be a priority here. The Plym has 10x2" original brakes, DeSoto has freshly built 12 x 2.5 brakes. Can I bolt up the backing plates of the DeS and use the bigger DeS shoes and drums onto the Plym king pin /spindle? Or, are the DeS spindles longer and heavier diameter for the hubs and bearings? I would have zero additional cost using DeS parts if possible. The question might become whether I need to change out the king pin /spindle AND the HD DeSoto coil spring to complete this upgrade. Your experienced knowledgeable comments needed and appreciated! Thanks Quote Link to comment Share on other sites More sharing options...
Booger Posted September 5, 2022 Report Share Posted September 5, 2022 sorry I cant help with the brakes..but I will say this. Thats a primo biz coupe. Some might say if youre going brakes why not the disc conversion? 1 Quote Link to comment Share on other sites More sharing options...

Some might say if youre going brakes why not the disc conversion? Because the "already rebuilt" DeSoto parts are already paid for and would be a significant upgrade in swept surface area. Thanks.
