I am thinking transmission mount, speedo cable, speedo gear, transmission crossmember, driveshaft and yolk, can all be re-used. Am I missing anything? Is there anything else that would have to be changed?

I think that is how it is spelt? 1957 Power wagon wm300 original 10.000 mile truck, 1964 dodge Polara Convertible numbers matching
