David,
The tunnel hump in the middle (between the seats) is cut to make room
for the Tremec housing. The crossmember at the front is not touched.
At the time I did the mod, there was no kit or anything available. Now
there is a kit from Tom Hall, and that is the way to go. Tom assisted me
with defining the minimum amount of cutting to install the transmission,
and then reinforcing the area. It is a very invasive installation.
It is not possible to shorten the input shaft and bellhousing to improve
the Tremec fit. The Tremec allows three positions for the shifter (I
used the rear most) but the middle hump must still be cut to allow room
for the transmission housing.
Another BIG improvement is the McLeod Centerforce bearing to eliminate
the clutch arm.

I've been considering various options re: 5 speed transmissions. Dale
A's modification is essentially unobtainable, although there was on ebay
that didn't meet reserve at $3080. I was interested in Curtis Fisher's
excellent article on installing a Tremec in his Tiger, but was concerned
about the amount of cutting of the crossmember required. He did mention
shortening the input shaft and bellhousing as an option. This would
provide a shortening of the unit, and allows the shift tower to be moved
a little forward of the crossmember area, the critical interference
area. How "doable" is this? What are the engineering limitations of
shortening an input shaft and bellhousing?
Has anyone tried this? David
