Tapered reamer and ball joint pain

[NeilW]

Anyone local got a tapered reamer for Sierra uprights?
Also is it just me or is it a nightmare trying to get upper wishbone ball joint to screw in....its tight as hell!
Tried screwing via the joint in situ but will end up knacking the boots, then tried spinning wishbone around hub but would need 2 weeks worth of weatabix to try again. Scratched the hell out the wishbones so will need to paint them again once I manage to screw the bloody joints in!
