Well it's a big ol fail. But tis ok - it's basically what I was taking apart at 12am last night, and had to bodge it back together to get it out of the garage, a new set of nuts and bolts will see it pass.
Pedantic choonts these MOT'ers eh?
P.S. anyone have the foggiest of where the hell I could find a full set of bolts and nuts for the suspension on a capri? Probably just strip it all down and go and find replacements for each one.
