Re: 7x1mm Bolts on PRV

["content22207" <brobertson@xxxx>]

Is actually a problem endemic to all PRV's, not DeLoreans (are there
even any 7mm bolts on remainder of car?)

If you ever do strip 7x1mm bolt hole, 5/16-24 taps VERY nicely as a
replacement. 1mm pitch translates into slight fraction more than 24
TPI. Tap will follow remaining threads as easily as bolt itself.

7mm hardware from industrial suppliers, but you need to order in bags
of 100. My local NAPA sells individually (grade 8.8), but cost about
45 cents each.
