belvedere666 Posted May 7, 2021 Report Share Posted May 7, 2021 I’m doing a rear end swap in my 50 Plymouth. this requires me to find an alternative for my rear shock mounts as the stock ones are on the spring perch. i have already had the new spring perches welded on the new rear end with no shock mount. ive heard that 40s Plymouth cars had a shock mount on the lower spring plate where the U-bolts mount. does anyone have a part number for this, and possibly some pictures, maybe some for sale??

Tooljunkie Posted May 7, 2021 Report Share Posted May 7, 2021 Usually the shock mount is part of the plate with 4 holes that the u bolts go through. Quote Link to comment Share on other sites More sharing options...

allbizz49 Posted May 7, 2021 Report Share Posted May 7, 2021 Cut the mounts off of the original perches and weld them onto the new ones. Also, lots of universal shock mounts out there. Summit, Jegs, all sell them. Can be welded to the housing. Quote Link to comment Share on other sites More sharing options...

Frank Gooz Posted May 7, 2021 Report Share Posted May 7, 2021 Depending on rear end tube diameter May be some thing like a Mopar rear lower plate that the u bolts go thought form a 8 3/4 ( 3 inch u bolts). Late 60's 70's or a pickup? Good luck Quote Link to comment Share on other sites More sharing options...
allbizz49 Posted May 7, 2021 Report Share Posted May 7, 2021 If you find a plate, make sure it matches your width of leaf spring. Personally, I wouldn't mess with a plate. Easy enough to weld some on the axle housing. 20 bucks and a little bit of welding, done deal. Quote Link to comment Share on other sites More sharing options...

Welding is an only an option if I load up the axle and take it to my friends house. In that case I would just have him weld bolts into the stock position. easier said than done at the moment. I was hoping to be able to locate, and use, the early Plymouth plates. I would be on the road a bit quicker. Quote Link to comment Share on other sites More sharing options...

Frank Gooz Posted May 12, 2021 Report Share Posted May 12, 2021 Do your shock point forward like my 48 Desoto or point inward at the top like my 50 Dodge and 70 Dodge. what is the rear tube diameter? 3 inch diameter the shock plate for a late 60's -70's Mopar 8 3/4 should help. The shocks on those cars were behind the rear end. just put the left one the right so the shocks in the front and so on. sounds like this would work in my head. Good luck.

I’ll look into those. Do those cars use 1.75” leaf springs? Quote Link to comment Share on other sites More sharing options...
Sniper Posted May 14, 2021 Report Share Posted May 14, 2021 No, they use 2.5" wide leafs Quote Link to comment Share on other sites More sharing options...
