Will this trans bolt up to my /6

First, what a deal! You will need a bell housing that is for a 4-speed or a newer one that had the dual 3 & 4 speed bolt locations. The tail shaft is that ball and trunion style so you need to change or modify your driveshaft. But the shifter and linkage will work, I think your z-bar will work too...and of course, you'll need a floor hump....:burnout:
