We ran a three speed in our pro-stock, never used first only second and third. With 5:86 gears you didn't need first. Alot of the guys would take out reverse and first to save weight, but it must not have mattered cause we beat anyway. I sponsor a Mopar dirt car, I can see if he has any trans but they're in PA. Maybe now hat you have some numbers A230 or A903 your search might get easier. The 230 would work fine as you don't need the sync's down to first, second and third are sync'd. Even if you found one with bad sync's you should be able to use it.
