Re: Fender bolts question

Mine were:

• The rear top and bottom of the fender use three (GR 5) 9/16" recessed hex bolts with integrated washers. The bolt threads for the LH fender were 3/8-16 x 1.1/4. The bolt threads for the RH fender were 3/8-16 x 1.1/8.

NOTES:
The 1.1/4 bolts are stamped with a double "F". The 1.1/8 bolts are stamped with an anchor.

• Each fender mounts to the gusset & core support using four (GR 5) 1/2" recessed hex tapered bolts with integrated washers. The bolt threads are 5/16-18 x 7/8. NOTE: The bolt heads are stamped "E".

With assys, the guide accts for 1000s of OEM identifications and part numbers, all written in short order. 700+ images include assm, illust., charts, and points of interest. Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
