Well guys guess what.... notmans idea of gears been wrong sizes seems to be the problme im not getting my hopes up yet but i went home and checked and the pinion gear is 14T and the diff gear is 48T hummmm let me think???
I like your idea of drilling bigger holes in the mounts i was also thinking about doing that too but its nice to know its been done and works fine before i did it.
I have checked out that website kengentry5000 and im going to leave it for now i think and wait till i got the cash then buy both the diff and pinion gear at the same time.
Thanks for all your help guys i think my worries may just have been sorted
(fingers crossed)
