Afternoon all,
I've bought an E30 to race, and whilst it did come with a differential, said differential was located in the boot, along with other bits of the car.
What size (Length, diameter, head size) bolts do I need?
The diff carrier is still fitted to the underside.
As far as I can see, there's some to bolt straight up, one to go through the bush a few to attach to the propshaft and a few more to attach to the axles.
Any help would be greatly appreciated.
Thanks,
Dan
