MY00 Subaru Impreza UK Turbo 2000 Wagon
failed the MOT today for a few little things, oddly the top bolt is missing on the NSF anti-roll bar linkage (How?!)
I'm going to try and get a replacement from a fastenings fabricator tomorrow but without taking the other side apart and taking it in to show them I don't know what to ask for.

 

If they are the plastic figure of 8 type then I think they are simply high tensile part threaded M8 bolts. Good grade stainless ones should do. The only tricky bit is finding one with a long enough non threaded part.
