First of all, I have a 1st gen RX-7 with a 12A and what appears to be a somewhat original shifter. I had heard on a non-racing forum that most of the Mazda shifters are interchangable. Anyone know if this is true?

My 1st choice would (probably) be to swap out what I have for a Miata shifter. They are shorter and therefore less prone to being "muscled" into gear. This is normally not a problem, as I've had the car for about a year and a half and am still working with the same transmission. FWIW, I change the lubricant after ever race weekend.

Thanks, in advance,
