904 pushbutton conversion
Imperial Services hasn't been around in awhile. If you want to run a push button shifter, you need a push button trans. As mentioned 1965 is the only year with a standard style slip yoke. But you need to use the manual valve, rooster comb and neutral switch from a 62-64 push button car. Or a entire 64 valve body. As long as it is a 77 or earlier non lock trans the later pump, front drum, and input shaft will retrofit to the push button trans allowing the use of the factory 360 converter.
