will this quaife diff work in my tranny?

[petevw]

i found a IRS Quaife diff for type1, that the guy uses with beetle CV's.

now i check on the quaife site and it lists 2 different items/part numbers:

VW - Type 1 IRS with 33T Type 1 splines
VW - Type 1 IRS with 37T Type 2 splines

what is the difference?

in my tranny i have a 4 spider diff using 10 tooth spider gears (not 11 tooth) with the super spline output shafts, which allow me to use 091 flanges and type2 CV's.

can i put this quaife in my tranny?
do i have to go back to bug output shafts?
can i keep my super spline type1/type2 output shafts?

anything else i should know?

thanks,
pete
