Are cossie 2wd front hubs/uprights, the same as standard sierra ones. Apart from the ABS sensors ?

hi the mushroom insert / shock hole is bigger (as is the 4x4 hub) not sure of any other differences though

Lower ball joint is not a taper fitting on the Cosworth

Yeah, just realised that when I've just tried them. Everything else seemed ok. Looks like I be swapping them then.
