hi rich
what ever you do dont weld the fooker dont be a mug mate

it horrible to drive not only that going around sharp corners it will skip like fook .. reversing it will be a pain in the ass and do your head in
ill gaurentee you will want to take it out
you have a few choices
you can either go
uprated planet gears with uprated VC to 240Nm on standard VC plates
which is about 10 times more preload on than standard (when it was brand new)
ATB this will do away with the planet gears
Gripper plated this will also do away with the planet gears
R n D plated this will also do away with the planet gears
all these still use the standard CWP
the weak point will be the CWP
9" diff V.C 3. brand new
9" diff platet brand new
the 7.5 uprated VC with the uprated planet gears is the cheapest option
less that 1/2 price against the plated or atb
so the choice is your mate
cheers marco
