Transfer cases

If you remove the selector from the side of the Ford case and use the chassis mounted selector, then a Ford case will mount into a Chev. If you mount a Chev case into a ford, although it will physically mount and the drive shafts will all line up, there will be no way to mount the gear selector.

The C8A/C8AX/F8A/C15A/F15A cases are single speed, and AFAIK they are the same dimensionally and internally, and being a single speed do not have the selector bracket issue mentioned above. That said, the case dimensions, drive shaft positions and many internal components are shared with the 2-speed cases. The basic difference is that the single speed cases lack the gear reduction components for low range, most of the other components being equal.

Tony is right ..as usual..
Chev used the Eaton two speed axle in their Chev and Maple Leaf trucks and Ford had their own two speed axle going back to the old Model T days when they used a two speed axle(Remember Ruckstel..??)...The only one old enough to remember those would be me and Brian and Barry,,..maybe Boobee..
And I don't know about Brain..the ex Mr Hupp.but Barry for sure..who is three days older than dirt..and almost as good looking as me.

Timken made two speed axles also as did other manufacturers..but Ford and Eaton were the biggies.
