Would anyone know the correct front and rear replacement shocks to put on a 1950 Plymouth 2 door Coupe? Engine and car components are all stock.
Go to an auto parts store. Have the counter person get a Monroe or other shock catalogue, compare the eye or stud mounts to your original shocks, the length compressed and extended, and have them order whatever fits. Or, look them up yourself. Google. A quick search showed literally dozens of retailers that you can order from.
You may want to consider relocating the top shock mount to the frame. The oem configuration, while interesting, is fairly ineffective.
I also recommend visiting P15-D24.com and reading up on the subject. I think there are some posts and pics specific to the relocation. In addition, Rockauto.com is a wealth of info on available parts and specs, whether or not you order there.. Best parts lookup on the web.
New shocks with the stock setup with the shock mounted to the upper and lower suspension members will still have the floater ride. The change to frame mounted upper mount makes a big difference.

Many moons ago I worked in a shop with a guy that had a '52 Dodge that needed shocks. We physically matched up some for a later Dodge Coronet, I would say 1968-ish. It had the same ends as his OG ones.
Monroe lists its #5752 shocks for the front and its #31000 shocks for the rear. Those probably are equivalent to the OEM shocks, but you might find them a bit soft. I substituted Monroe #555002 in front and Monroe #58567 in back. The former is listed as an RV shock and the latter is a coil-over shock sometimes listed for this application. They have the same dimensions and mountings but are much firmer.
