The only thing different between the 64 and 65 front ends would be the spindles and brake parts, if one has 9 inch brakes, and the other has 10 inch brakes.
Thanks for the help, I will prob stick with 9" drums, save all the parts from the 65 until I switch over the master cyl and do it all at once, control arms will just have to be returned and new small ball joints will do!
