The Ford SROD from mid '70's to mid '80's can be fitted to a Model A. I have one in my Speedster. The shift lever is mounted on the tailhousing, so it sits up to 6" further back. There are several versions and where the shifter is mounted on the tailhouse varies. I have found only two % of OD - the 37% and 41%. I dont think they have a 26%.

Not all the internals are the same. The output and input shaft and bearings are different, so it is almost impossible to get the 26% by changing internals.

Since shifter is on tailhouse, thus using the long original tailshaft, you must use an open driveline. I will try to get pictures of my Speedster shifter and driveline when the sun comes out.
