I purchased the end-mount rubber insulators from Banzai for the rear bumper on my '71, but I seemed to have misplaced the bolts that attach the ends of rear bumper to the sides of the body. Does anyone know the correct size & length of these bolts?

Thanks

The correct size is an M10 x 20mm long Hex Bolt with a "4" marked on the head.

Thanks Redzedsled!
