Thanks ian, i did believe i could use the standard sump after some machining, so that is a good thing that i can spare that expense.

But do you know if the standard grp a driveshaft will fit directly on the lobro i have?
I guess the other end of the r&d xshaft is the same aswell, so if the grp a items fit im probably sorted as long as i fix the hub issue.

Do you or anyone know who supplies grp a shafts?
Should probably get the tarmac parts as i believe these are thicker?
Do you know the different lengts of tarmac/gravel compared to standard 4x4 driveshafts?
