So i've been experiencing a pretty big clunk in the front end of my car, i figured it was just a loose engine mount.

i finally decided to have a look and it seems that i am MISSING the bolt on the rear of the lower wishbone!

Can anyone help with either a replacement of a place to get a replacement?

I'm assuming my mechanic didnt use any loctite when he replaced the bushes for me. I'm pretty pissed off!
