I had my cousin slot the holes in the calipers and they look great.
Roadworthy was knocked back due to a big rust hole in the engine bay under the heater bubble. A dodgy repair was done with fibreglass and the mechainc attacked it with an F'n big srewdriver and mallet and ripped up half the firewall. He really hooked in to the point I was about to give him one.
So new plans are to strip the shell, fix all the rust & have a crack at repainting it myself.
Sounds easy in theory but we shall see.
Here are the calipers.
