Serious 64/65 904 trans question

The 65 floor shifter has 2 cables coming out of it, one for the selector and one for the brake pawl at the rear if that helps. If your going to do any trans work, the 66 and up use a more standard PRND21 pattern and use a linkage, and use the slip yoke in the back, not the "Detroit" aka Ball and trunion joint and then there is the driveshaft mod for the slip, etc. Yadda yadda, if I knew all this I would have fixed my 65's! I still have the old shifter.
