Hitch install bolts
Hey, I found a used hitch for my 94 150. My frame rails are not drilled like the newer trucks. Each rail takes 3 bolts. Are 1/2" Grade 8 large enough or do I need larger dia. ?

Larger Please...
Most new hitches come with 9/16-5/8 for a class II
I've seen some class III's with up to 3/4" mounting bolts.
Measure the hole that is pre-drilled in the reciever where it bolts to the truck frame.... use that size bolt. Those are drilled to a particular size for a reason.
