won't go in gear

Ok. I have everything apart. I checked the pilot bushing with the input shaft. It is very snug I can turn the shaft in the bushing but it does take some effort. I tried the new spare bushing I have and it spins freely on the shaft. I guess it swelled a little when I installed it. I think this may have a lot to do with my problem. I am going to go ahead and check the bellhousing offset anyway before I put it back together. It will be wednesday before I get my dial indicator.
