So I just ran across a deal, 5spd ZF S5D 310 Z with clutch, flywheel, hyd. cylinders, shifter and pedal assembly. All for 400. My question is, what else am I going to be needing?

Driveshaft, trans support brace, interior panels, that sort of thing. Based on your previous thred, if this is going on a M60B30, you need to verify that it has the right bellhousing.

That's what I'm in the process of doing now.

And if it's not, then pass along the info because I need some of that stuff. :)
