The "Screw w/Washer, Rear Hanger Mtg."'s on the GLHS need replacing. In lieu of walking the aisles at the hardware store looking for a comparable replacement, what Chrysler documentation am I missing that would give size and thread of an individual screw?

The Service Manuals show the bolts, where they go, and what torque spec to use.
My 1986 Parts Catalog shows part number and description (#6501165) but no sizing.

Were sizes given anywhere?
