Ernest,

No I do not have personal knowledge about what gears will interchange

betweem the early Ford C6 transmission (As used in "Ross" redrive) and

the late Ford E4OD transmission (With 6 planet gears & steel housing).......

I do know one thing.......I would not advise using a 3 planet unit with

a possible 200 hp 13B rotary !! I do have a 4 planet "Ross" 2.85 redrive and

Tracy's 6 planet 2.85 "RD1C" redrive.......If you will send me your sun gear

I can tell you if it will mesh with both the 4 and 6 planet housings I have !

Hopefully Tracy will jump in here and give you some "Real World Info"

regarding what will fit what !!
