Get a shot of where the levers come out of the floor on your photobucket account and the measurement of the floor openings, I may be able to fabricate something. I'll have to see what I have for materials, but I have a couple shades of vinyl nagahyde available around here somewhere.
I made a dual boot for my dump levers and a boot for my shifter and brake. Didn't go for fancy, just sewed them to the carpet insulation and cut the rubber mat to fit over that. Came out pretty clean and does the job nicely.

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
