Just to add a bit to what Charlie has already stated…
The Ranger Overdrive is seven inches long. Advance Adapters makes the
Ranger with front faces for the modern Dodges with the 5.125" bell housing
index with 1"x23 spline shaft but not the older Dodges. Other front
ends for Ranges include GM with 4.486" or 5.125" index with 1-1/8"x10 spline,
Ford 4.484" or 5.125" with 1-1/16"x10 spline. My deal with them is for
GM front ends with the 5.125" index with a rear end that is set up for the
older Dodge 1"x10 spline input shaft and a 4.75" diameter bearing retainer.
They are not drilling the transmission mounting holes in the rear face of
the overdrive in order that they can be drilled at a local shop to match the
transmission actually used.
To put one of these between a motor using something other than a Chevy
bellhousing and the stock transmission: Enlarge the index hole in the
bellhousing to 5.125" to fit the Ranger Overdrive. Drill new mounting
holes in the bellhousing to match the Overdrive or vise versa. Change the
clutch so that you have one that is compatible with the input shaft used
on the Ranger (in my case the 1-1/8"x10 spline). Use an extended pilot
bushing since the input shaft on the Ranger is a bit short. Trim off the
excess length on the input shaft of the stock transmission so that it will
fit properly into the Ranger.
To the best of my knowledge, Advance Adapters has discontinued making the
electric shift Ranger Overdrive, so plan on adding another shift lever...
The Ranger is available in both Overdrive and Underdrive versions. The
Overdrive is a 27% overdrive; the Underdrive is a 17% underdrive.
