Rear Bumper Bolt Sizes

80sRich · Jun 13th, 2011, 17:14

Hi Guys,

Whilst looking around the car before taking it for a run I noticed that the restorers have only put the rear bumper on with two bolts. This is despite me giving them all the original bolts when I gave them the bumper back.

Anyway, I was wondering if someone knew the size of the bolts that go into the bumper from inside the car so that I can replace them. Or if some kind soul could measure them for me.

PS. Took it for a test drive anyway, with a new clutch, flushed out system, new thermostat, 4 new pads and 4 new discs it was a fantastic.
