Hemi 4 Speed?

I have the slickshift 18-spline 4-speed parts from the Crazee 'cuda pro stocker...another Hemi 'cuda. I'm not sure they are particularly significant except to that car, and it had many transmissions.
HOWEVER, it sounds like you have a pair of slickshift 4-speeds. They will be miserable transmissions for ANY hotrod driven on the street. Slickshift transmissions cannot be down shifted there are no gear cones. I have to shut the car off to get it into a lower gear. If I were you I would sell the pair and get a synchronized 4-speed. Trust me, you will be much happier with the final result.
