'61-'62 rear bumper bolt

[Michael K.]

Can anyone verify the specs on the pointed bolts used in the rear center bumper on a '61 ? There are 2 different lenghts used. I need the lenghths of the threads and of the total length from head to tip. Thanks, Mike

mike, the bolts on the 62 i'm just finishing up are, of 7/16 " #14 NC threads, 5/8 " head, the short one has a WB1C mark and is 1 1/2 " top of the head to the point, the longer one is a WB and is 1 7/8" top to point.

Doug -

In terms of ID'ing a bolt or specifying what you need from a supplier as a replacement, bolt lengths are expressed from the underside of the head to the tip (shown in many fastener supplier charts as "UHL" - under-head length).
