32, I haven't seen very many of these, but on all I've seen they have a side shift with linkage like all the old car 3 & 4 speeds, muncie,saginaw, etc. None come up in the center as far as I know. You need an S10 5 spd. Another possibility is Ford used a similar trans in the 80's. They were a top loader 4 spd with 4th as OD. On a lot of these, they used a center shifter, although it was mounted pretty far back. You could adapt it to a Chevy bellhousing with a little work. Maybe this will help. Joe
