your only needing the servo saver arm, id suggest both the front and rear gearbox holders, dont just do one!
finally the hingepins are a fortune! ive a set of 410 titanium pins left but only have one set of inners front and rear left. tresrey are massively over priced, set i have is £12.50 delivered. 50% stronger and 50% lighter as well
the rest is bling, dont get the mid drivshafts they wear like butter, but the front and rear hubs are nice to finish it off.
