Does anyone know something about a ball joint for sierra uprights.
I prefer the pressfit-type (similar to VW-beetle) with an outer dia of 43mm an a 7* taper of 15.5mm. Otherwise i'll have to ream the lower hole's in the upright.
The lower arm is now equipped with a chevette/kadett 1.6-2.0 ball-joint 43mm, 7*, 14.5mm taper (for cortina uprights).
