Hi and welcome.
Yeah, it's been a bit slow for a while. Good to have new blood ! There's a few old timers that check in, without posting, but may chime in if they can help with a problem.
Yes, there are many wagon (Conestoga) parts available. You don't say what you may be needing, but...
Studebaker International is the overall main site to look for reproduction parts, they even have NOS parts. Many other backyard shops are also ready to help with good reproduction parts.
Most all chassis parts interchange between all Studebakers, especially the front. The rears, the 53 to 55 use a different leaf spring, but the bushings are available.
And of course, guys that have "take-off" parts at home.
Want an updated trans, there's a coupla guy selling adapters to install GM transmissions behind your Stude engine. I have two ! GM, T-200-4R bolted behind my Stude engines (I have two Conestogas).
There's also the "Racing Studebaker" site if you want to hot rod your wagon.
https://racingstudebakers.com/foo/There's a couple of us that have figured out what it takes to make Stude cylinder heads flow well for mileage and performance work. One guy has built adapter plates to instal small Chevy intake manifolds when you have your heads ported so all that head work actually helps.
Post some photos and your needs when you get the car home.
Have fun with it.
Mike
