The Stovebolt Site Forums The Shop Area Driveline T5 Shifter Boot Suggestions Wanted

I've installed a T5 in my 55.1 3100. I used a short-throw Mustang shifter, so my hole in the floor is 4".
I'm looking for a shift boot that will cover this and be tall enough for the Mustang shift tower (about 3").
The small round Mr. Gasket one and the one for a Jeep T5 look promising.
None of the FLAPS seem to have any in stock that I can go look at and measure.
Does anyone have any suggestions or experience to share?
Thanks.

Leon
