01A questions

[David.Payne at brinksinc.com]

What cars did this gearbox come in?  2wd and Quattro?  Are the individual
gears interchangeable, between gearboxes, and between positions inside the
gearbox (i.e. can the 3rd gear set be used in the 4th gear location etc.)?
The Porsche 901, 915, and G50 have this capability (within each size) and
makes it pretty easy to pick and choose the ratios you want.
Can a 01E be installed in place of a 01A, and does the 01E have the
capability to change ratios?
Looking at the microfiche for a 90 Quattro, it looks like you might be able
to move the gears around.
TIA
Dave.
