Welcome to CHR Ronnie! That sounds like a very nice project you have going on. A good friend of mine is working on a 51 Chevy sedan and just put a MII set up under the front. I can't really help you with if you can use the front suspension from your donor or if you'd even want to due to the set up of it. You might be able to use the rear end under your 52 though. I'm sure some others on here will have better info on that for you.
