Back in the day Sparkomatic was the king of home made shifter kits.You got the shifter,mounting bracket,and 5 lbs of shift rods,and angle iron bits,and pieces.JC Whitney might still sell it.You might find a kit at a swap meet.
I just went to the speed shop and bought a floor shifter and put it in, but I guess that they are not as common now as it was back then. Put the transmission in neutral, line up the shift levers with the drift pin and adjust the length of the arms.
I bought a rusted heap, took the drive train out (along with shifter and linkage) and parted the rest out. Then cut a hole in the floor.
Did't I just sell you a shifter? Maybe a different transmission; the numbers look "Ford"? I may still be able to help. I am Butch/56asedandelivery.
The Hurst shifter towers (the actual shifter part) is virtually the same for all floor shift conversions by Hurst. Then you also get a "kit" to mount the tower to the trans and the rods/levers. I have lots of Hurst tower assemblies. ritterdavid sells a lot of Hurst stuff in the classifieds here on the HAMB. Plus there are usually some fairly good deals on that auction site we all know and love. Personally, I'd stay away from any of the "cheap" shifters, that really are't cheap. I'd let you have a good, used, Hurst Synchro-Loc for shipping only; trying to thin the herd of some of the stuff I have. Just PM me if interested. I am Butch/56sedandelivery.
