Same here. Hurst no longer sells the kit but you can buy the brackets still. The one thing I didn't like about the mount was how it clipped part of the exhaust reliefs in the torsion bar mount. otherwise a beefy piece.
As others stated you'll need to cut the floor and widen it for a unmodified TKO or T56. SST sell ones that are supposed to drop in but $$$$. I used the SST shifter handle, as the shifter mounting moved closer to the center of the car. I also added a console, which requires the brackets to be reworked and the console body to be shaved down to fit the new floor plan to place it in the original location.
With the TKO I was able to reuse my 4 speed drive shaft with a conversion u-joint and use the yoke Hurst supplied.
The aluminum bell that came with my kit required the 72-up bell z bar pivot to accurately locate the Z-bar.
Last I looked kits from American Powertain don't include a bell housing.
