So my sync from 2nd to first is GONE, and i have a donor tranny but as my luck would have it, the yolk on the donor is a 4 bolt and the one for my drive shaft is a 3, they dont match SO i need a 30mm socket to get it off, no one has one with a thin enuf wall, Is there a special tool i need to get it off or something? or is this like a dealership thing only?!
