I usually get my stuff from
Mustangs Unlimited cause its close to me. They have the B&M shifter, and ashtray switch panel. Other places sell them too, for around the same price.
As far as a boot cover, one comes with the B&M shifter, but a Stock 5-speed shifter cover will cost like 80 bucks new, so get one out of a junk yard for cheap if that's what your looking for.
I used vynal interior paint, but not the stuff from the autoparts store. That stuff is junk! It has to be flexible paint, and the pieces being painted must be cleaned! I also used black parts from a donor car so everything was not painted.
