I’m structure a 4wd sand cart formed upon a Suzuki Sierra framework that we wish to repower with a identical tiwn cam efi 4cyl or rotary. Not overly fussed upon a engine as many can be worked easily. So suspicion we would ask about a trans so we know that rwd half cut to buy.

Mazda s’ are probably your best beat as all the old cars came with rear wheel drive transmission, don’t you want to go manual? You would have a much larger choice, but if you don’t want to Mazda made auto trans form 1980 onwards. There are tons of automatic trans axle gearboxes form 4cyl but would not probably suit your needs.
