different Porsche trannies?

[Michael Ghia]

I ran 914 output shafts on my 901 in my Oval with no problems. It originally ran 930 output shafts.
I've swapped the 930 shafts into my 915 box (originally from my 901) and now have a pair of 944/T2 size shafts spare.
My 901 box was a 69. It may be that the earlier 901 boxes (with push type clutch, 1965-69) use smaller seals. You might be able to get around this by putting later seals into it.
