Done 2 sets this week alone.
1 set on my mates Pug we build last week (put them on last Saturday) and some on my other mates Focus as he liked them on the Pug
Gra to stop the rivet in the back one from sticking up I put 3 tiny little nuts under the head of the rivet gun, this spaces it out of the channel and allows the rivet to be popped properly
Simple job, you soon get used to drilling holes in bonnets pretty quick
Ours we use are the stainless ones from Rally Design, the alloy ones wear out too quick

£5 a set without all the packaging
