I am installing new leaf springs on my '55 Club Sedan and have discovered that the front hanger bolt is a specialized item B5AZ-5780-A.  In essence it is an approximately 3 1/2" long shoulder bolt with a 7/16" shaft and a 3/8" NF threaded section.  Mine are shot and no one seems to have this part.  I am thinking of reaming out the inside (3/8") hole in the hanger to 7/16" and using a straight 7/16" bolt.and and nylock nut.  Has anyone encountered this?
