anyone know where to get the modified carriage bolts for the back of the fender. 3 bolts for each side. Is the bottom bolt longer? I have never had the proper bottom bolt on the fender for as long as I have had the vehicle

Thanks Marc

 

MARC The part number for those is B7C-16584-A. Here is a thread discusing them.

Looks like the junk yard is going to be your best bet, that is what I had to do, I needed two of them.
Good luck in your quest!
