Guys, thanks for all your input.
I must have the wrong fender on my truck? Duke and Ken1960 have over 3" of clearance between the cab and the fender mount spare tire. I have zero clearance with the stock 670-15 tire? I bought the fenders I am using at a local swap meet here in Colorado, they are not original to my truck.
Were there different styles of stepside bed fenders with the spare tire cutouts? I have ordered a 640-15 tire as a spare, so it should have a 1/2" clearance, but I am confused as to why there is a difference.
I have pictures of the truck in the link below.
Thanks,
John
