You'll need a hard to find TH400 version with a 32 spline input.

best way is the 32 spline 203 range box, you dont need the adaptor. then use a newer round bolt pattern adaptor from like a 241 tcase or such. redrill the 203 face and tap the holes. then do the dubbler.

this is the most comon way i have read every one doing.
