Sorry about stealing the 710 thread, but I know you guys might have these parts...used are good enough for me, but must be usuable.
Serpent Impulse rear gear diff (all the gears inside must all work, I have to replace some of the gear inside my old rear diff that are broken)
Serpent # 801415 - 2-speed axle 4WD 705-835 and
Serpent # 6357 - Ball Diff pulley 46T Impact/Impulse/705
Thats all, PM me...............thanks again.
