Hey all, other than having to make custom mounts and a custom drive shaft what are the pros/cons of using a 1st gen short pinion set-up?

Mazdatrix used to carry an adapter to put 1st gen gear sets into the FC - it was sort of a shaft extender. I don't know if these are still available but it would make your job a whole lot easier.

My dad suggested this the other day when we bought a GXL diff. He thought that the smaller FB/SA steel differential part would be lighter. Is there a big difference?

I think I am going to just say screw it and get 4.3 from a GTUs or get a them new.
