Outer Limits 4x4 Board

iv done a search and cant find if i can put rears up with the j arm steering i was thinking of putin a limiting strap on the drives side to fix it but will it still reach with the diff forwad and how far willl it go forwward

From what Ive read, RUF will move the front diff forward about 35mm ish.
I think you can still run the original J arm to drivers wheel, but you may need a dropped draglink to keep it running nicely, otherwise just go crossover or hi steer.
There already should be a torque rod holding the front diff to the chassis, if its the stock one, then you may need an adjustable one to handle the diff being moved forward.
If you go crossover or hi steer, you wont need a torque rod at all.
Hope this helps.

yer cheers mate im geting a drop draglink made and i was ganna cut and shut the toqure rod

You can buy them from Superior and Locktup and Snake, etc.
Or if you can hold out for a month or so, Ill sell you mine, its made by Superior and adjustable at both ends.
