So, is the GSJ 269 and QH1060 ball joint considered to be a better bet than the GSJ 268 and QH1059S now? I have a "new" old stock QH1059S that is 14mm wide at the top of the taper, the specification must have been correct at one time? I only ask as I will update the info for the Alternative Parts List if you can confirm that GSJ 269 is the correct item, or MOOG RO-BJ-3409?? I will add to check the top of the taper is 14mm dia for now.
Impressed that you got the ball joint off with a big spanner and a long piece of pipe R1NGA, only an impact wrench would move mine.
I'll wait to see what comes in my next couple of deliveries - I've ordered a pair of the MOOGs that Roger found (despite being onlinecarparts.co.uk, they're actually based in Berlin), so there's a chance that these might be correct. As these might take a while to arrive, I've also ordered what looks like an old First Line FBJ5150 from FleaBay as I need to get the car driveable again and it might come faster. Sod's law says these all pitch up with the small 13mm taper, but let's see eh ?! Thanks again for everyone's help in trying to bottom this one out.
