I hate getting rid of the original parts if they can reasonably be serviced and put back into use , as it is, I managed to find a replacement universal joint from JMB for around 22.00, and am just getting it pressed in at the moment.Instead of faffing around with a uj, why don't you try to get hold of the complete steering rod assembly? Try Minksport on here, he may have one.
Sorry, I have only just seen this post and realised that I had posted the wrong photo!dcrobbo, what is the part number for that GMB u-joint?
Isn't it a shame when someone finds the answer but doesn't bother to post details to help others.
