It is much more plentiful (at least in the US) than the 722.2 which you have. I would also try to source it in Europe. You could check with Stretch/Army and Cho. There are some modifications required, the most significant being shortening of the driveshaft (the bell housing is 3/4-1" longer)."

If you are bent on maintaining originality, then rebuild the 722.2 trans, however, replacing with a 722.0 type, will be the more satisfactory solution I think. MB discontinued use of the 722.2 with V8s after your car, and discontinued use with the I6s in mid-1973!
