Hi All

I'd like some advice particularly from the racing crowd on the direction I should take building an aluminum 901 box.

The box I'll be using currently has the rare 904 LSD and I have both CV and Nadella flanges to choose from. To be honest as I'm not required to run the original differential, I'm inclined to go with a Guard LSD and move the 904 diff and flanges to someone who must use these.

Is anyone running the guard in a 901 box and SWB?

If I move away from Nadellas to CV, can I use a LWB hub in the SWB swing arm? I have a spare set of 69 drive shafts and CVs.

What are the best type and length of CV shaft I should be chasing? I know I can specify which output flanges I need to Guard. But is suspect there is drive shaft length differences depending on the overall combination of flanges?

I hope I'm making sense? Thanks for any advice.
