Please measure and map that rod pass through hole for the rest of us - I've got a complete St400 set up for my 65 Conv, and I'd really like to be sure where to cut for the boot.
Will do but it will be 3-4 weeks at least given my schedule and Stacey's schedule. He is going to ship me the hump he cut out of a 67 GS400 parts car so I can accurately figure out where my console goes and where the hole for the linkage should be cut. I will post a photo story of how it goes and critical dimensions. Here is a picture I received from another Forum member showing the rubber boot and how it is configured which I was not sure of since the boot I received with the shifter I bought was dried out and disintegrated. Hope it helps.
If you want more detents on these shifters, you can add a detent plate to the bottom.... so it works when the lock button is pushed down. I did this to my 2 speed '66 shifter when I put a 3 speed st400 in it back around 1986. I did it for strip use. There's a stop for the 1-2 shift, and a stop for the 2-3 shift.
Intersting picture chucknixon, I've never seen a 67 shifter installed and that gives me a much better idea of how the pass through plate it oriented to the shifter base. I wonder if the floor of my 65 has that same bump which supports the LR corner of the plate? Walt, I've also heard the position of the shift rod pass through on a ST300 shifter interferes with the larger case of the St400 - did you find that to be true?
Rhett, the early shifter will have interference with a st400. But the lever that goes thru the floor can be bent and ground to clear.
Walt - if next time you're under there you could snap a shot of how you modified that arm, and the additional detent notch in the plate (or did you sub an aftermarket detent plate? I know someone makes them somewhere...)
I am thinking 64/7 detents are part of the shifter body. Some 68/72 are removable and I have made new ones for my 70 to do like Walt stated.
