I went to a T5 from an 84 Camaro and had to move the cross-member back a bit, the frame has an extra set of holes that were in the right position for the T5 trans mount. Using a torpedo level across the intake manifold carb base and lifting the back of the trans until the carb pad was level, determined the height of the cross-member mount. If I recall the engine/trans is tilted 6 degrees down when the carb base is level. The mount had to be made tilted because the tailshaft pad is 16 degrees tilted. Ground clearance is not a problem.
