Rear shocks: bolt sizes for the top mounts

[Mew]

Went to fit my koni adjustable shocks over the weekend and had a spot of bother with the rear shocks.

Basically, took the top and bottom mounts off the original shocks and tried putting them on the koni's. The actual mounts fit over the koni's, but the bolts and washers don't! Is it just a case of me going down the local autofactors with the koni's and seeing what fits, or are there particular parts that anyone knows of that i should be using?

It's the bolts and cup shaped washers that go either side of these that don't fit the threaded bit of the koni:

I think the rod size is a bit thicker, you should get new nuts with the kit.
The bits you are showing are the bushes, just open up the middle a bit, should fit
