Hey andy - i'm assuming this diff will fit in the front and rear??
Any option to the front drive shaft cup/holder? the plastic 'nipples' and the metal 'nipples' don't always like playing together nice and the plastic ones break...
the is the plastic piece that hold the drive shaft and connect to the front diff bevel gear
a metal one like the one in the rear would be nice - or else a composite bevel gear that would work in the car
