Complete 3 Speed.... Your thoughts !!!!

That Aluminum Small Block bell housing is worth 250. See them for sale at the swap meets for that, works with 4 speeds too.

Someone may want to go 3 speed on the floor from a wore out 3 on the Tree set up ??

Some earlier manual 3 speeds were a non-syncro first gear. So the 72 probably has a synchronized first gear, so that can be an upgrade for someone who has a non-syncro first gear 3 speed trans.
