like u say having beam modified to accept supra diff might be better option, but i paid £1200 for 6deg beam £450 for fitting kit £300 for cover theres nrly 2grand!
i myself would prefer beam modded to have diif bolt too rather than loads of seperate pieces, but at what cost. i paid £270 for diff , £580 to Bara to be checked over n weir kit fitted £2800 all in. its lot of money really when you think about it. but isnt supra diff rated to 1000bhp
