Hi all,

Has anyone converted an SM319 o/d tranny to floor shift? I thought id ask how you did it before I reinvent the wheel.

I had a floor shift kit for a over-drive transmission , never used it ,it came with a over-drive transmission I bought from a junk yard that was closing out, I think I've still got it . they where different that the regular three speed,

I have used a Hurst Mystery shifter on a SM318 with a BW over drive. I don't think a 318 is that much different than a 319. Hurst built a bracket for an OD in the 60's. I have seen them on eBay, but it wouldn't be that difficult to fabricate. Room has to be left for the shift solenoid. The trickiest thing is clocking the shift levers. I have made them work by cutting the lever at the transmission in an arc conforming to the arc on the levers. I then put everything in neutral and weld it. Its not quite as simple as it sounds, but it works with a little trial and error. Care must also be taken that the throw is correct. You want to make sure the transmission goes all the way in gear. This sometimes requires shortening the levers a little.

Made my own, or I should say, altered a B&M shifter. This has been in place for 10+ years. Made an up-over-up bracket to attach the shifter away from the leg to the middle of the floor. In the first picture you see that I shortened the shifter arms and welded them in place. The shift pattern is conventional three speed. Middle of floor with an after-market boot.

Cosmo, Thanks for the pics. I am inspired.
