T56
 

Having a bit of a weird issue.

I picked up an LT1 T56 a while back. Bought the RS Gear LT1/LS1 input and midplate kit to upgrade to fit the LS1 bell. Trans shifted fine on the bench prior. During the swap, the shift rail on the counter shaft, I believe it is the 5/6 shaft, dropped out of the alignment with the guide bolt, allowing the shaft to drop about 1/4 inch to where the shaft wouldn't go into the boss hole in the plate. so on the advice of RS gear, I removed the guide bolt and that allowed me to get the midplate installed correctly. Got it all back together, went to shift it, its stuck in gear. wont go out, I removed the guide pin to see if that would help, it didn't. Any thoughts as to what could be the problem before I completely tear this thing down and rebuild it?
