I managed to damage the thread on both upper balljoints of my Indy, when I tried to adjust the camber (don't ask).
I want to run to the local parts supplier, but need to know what to ask for. All I know is that they come from a Transit, but at the shop they'll ask me; what year, which balljoint, etc.etc. I haven't got a clue!

Does anyone have a part number? And is left and right the same?

RalDes are (or at least were) doing some barginaceous bargins on swivel joints... and their customer service is pretty good...

best to use the QH reference it is unofficial industry standard

Thanks for the rapid responses. I have been able to order some. But here in Holland that's no easy job! Two local car-parts shops were not able to supply them, and the local Ford-dealer wasn't able to order them either!

Luckily there is a small kitcar-community here in Holland to, with its own little supply chain.
