so over the winter i took my transmission apart and replaced all synchros with carbon coated ones and put an ls fifth gear in it. the trans is a gsr with quaiffe lsd. i installed the diff about two years ago and that went fine. but after disassembling my gearsets, im assuming i did something wrong. in neutral the car wont roll, it acts like its in gear pretty much. also none of the gears seem to fully engage except for reverse, and it wont even go into fifth. i havent tried to drive on it or anything because im still working out some bugs in the motor, but i have started it on jackstands and it wont even run in neutral, something is binding. i plan on taking it out tonight, but i figured i would post on here to see if anyone could make any suggestions or give any input as to what i did wrong. thanks
