Front Coil Springs - Which Part is Correct?

I'd take a look at the pinch bolt first and see the state of it. The pinch bolts on my mk1 were fine enought to reuse but I'm amazed I managed to reuse the ones on my mk2, they were very crusty and I thought I'd have to cut them off and take the ones from the mk1. If I realised they would take so much time to remove I would have just bought new ones for a few pounds and been done with it. Also the top mount bolts would be fine to reuse, I think I either reused the ones on my mk1 or the used bolts on the coilovers I put on either way perfectly fine.

And if you're changing them yourself get a proper spreader tool, you can do it with a chisel, an 1/8" drive wedged into the hub and turned 45 degrees works to an extent too. But a proper spreader tool will save you SO much ballache trust me.
