I have no issues with anyone just a warning to us all at loads of people offer advice without doiung such mods.
If you really wanna spin up all 4 wheels without any breakage issues you will need somting like ashcroft driveshafts 4 pin, pinned front and rear diffs, lockers if you relly want and ashcroft Cv's but you will always be moving the weak point somwhere else up th edrive line.
Best park of £1200 front axle and £1000 rear 3 speed auto box from an early RR Calssic (clunky but indestructable ish) built and designes for chevy v8's find some kind of strengthened tranny box mabe use a series transfer box instead of a LT230 I have seen conversions about sonwhere and then your about as bullet proof as you get. The above is usually a goo dstarting point for a trials vehicle minus diff locks (not legal in some comps)
