So, when you swap the main drive in…can the gears from the early trans stay with it? Sorry for the dumb questions, but I’ve never been inside an 833. Like most all old men start a sentence about cars, “Back in my day, if a 4 speed didn’t work right…we’d pull it out and go pay $25 for one at the junkyard that did!” LOL

These are the parts that have to be replaced. They are B-body B&T parts but it's the same idea. '66-up speedometer parts are also required. The 3.09 main case and with input and cluster gear can stay together unless the bearings need to be replaced.
