I have a 62 Chevy c10 I'm restoring. It's currently frame off and I'm having difficulties removing the 3 speed from the bell housing. I have removed the tail shaft, trans mounting bolts and side cover/shifter assembly. I can't seem to get it to come off the guide pins. I've pried on it over and over, it won't budge. The gears are in neutral. Thanks for any help bowtier
