transmission ?'s

Im new to this forum thing and I dont know if I'm doing this right. I have some question that I cant seem to find answers to. I have what I think is a sm420 4-speed, a spicer dana 18 transfer case, and the original T90 trans. I have all the mounts and a bunch of extra parts. My dad was going to put a 350 in his willys but never got to it. So I have these parts now but no willys to put them in. Anyway I'm wanting to sell it all and was wondering if someone could help me ballbark there worth? The t90 that came out of his willys is toast but everything esle was in working order when they were removed from what they were in. I have some pics. but I dont know what other info to tell you guys. Thanks for any feedback you might have.
