Source of 833 Transmission Mount?

How far along in your Swap are you?
Did all your Clutch Linkage work okay?

I have removed the 3 speed gearbox, but the bell housing is still attached to the engine in the car (in the process of removing the engine also). I have also cut the transmission tunnel to accommodate the 4 speed.......moving very slowly.

I actually cut the tunnel first to get access to the top, left transmission to bell housing bolt. I am considering installing the transmission tunnel with bolts and glue so it can be removed to get access to that bolt when needed, and to aid in linkage rod adjustment.
