Yep, I read about that. If you grind the lockout part of the lockout plate down some it becomes disabled, and 1st gear will be in the location that reverse once occupied in the 4 speed shift pattern.
It can be done, but it may not shift perfectly.
CV's are the same as Type I if you have a 914/901, except there's two dowel holes and 4 bolts in the 914 flanges, and 6 bolts in the Type I flanges. Time-cert the 2 holes in the 914 flanges and your'e good to go with stock Type I CV's.
Flipping the diff is pretty easy, but you do have to take the gear stacks and intermediate plate out to get the pinion gear and input shaft out of the way of the diff carrier assembly. I was lucky with mine. I didn't have to change the pinion depth to correct an improper wear pattern in the ring and pinion gears.
Here's what you'll need:
-You got stock control arms? Use stock CV's and axles.
-944 control arms? Use Type I inner CV, Type II outer CV's on stock axles
-late 931,932,951,952,968 control arms? Use Type I inner CV, Type II outer
CV on 21", 33 spline Porsche axles.
-Longer clutch cable
-911/901 selector rod. This is refered to as the "hockey stick", but it's actually a 30" rod that goes halfway thru the transmission, and MUST be obtained, along with the 901 front housing. One can be fab'd from a VW hockey stick, and a 914/901 tailshift selector rod, but it must be straight.
then theres the crossmember,..
