66 273 to a 65 A833 and all into 67 dart?

Yup- even the Maxies & Hemis ran through ball & trunions. Nothing wrong with them. The biggest problem is that it's getting difficult to find rebuild/service kits for them, so most people end up going with the adapter setup now.
Hell, B&Ts are still being used on new cars, probably more so than U joints. They just call them CVs now.
Thanks again for all the thoughts and ideas guys!!!
