Bed and Body Mount Bolts

[gijon]

Does anyone know the dimensions of the bed bolts and body mount bolts?
I am replacing rusted out brackets and body mount bushings, and need to know what size the bolts are to order new ones (I haven't torn anything apart yet). No one seems to know how long the bolts are (napa, autozone, etc.). I have found on the forums that I should use 1/2" grade 8 bolts for all, but just need to know how long they are.

I did start to remove the bed bolts and have already broken 2 of them . I would like to replace them with standard head bolts rather than these f'ing torx head. From the broken pieces I think they are approximately 4 1/2" bolts.

Any help on the sizes of these would be greatly appreciated. Thanks!

I bought some 8" bolts and they worked perfectly...grade 8, of course...I think you can legally get away with grade 5...but for an extra buck or two may as well get the best ones...

The bed bolts are usually Torx heads, but I replaced all mine with hex-heads...and washers...and painted them with rust paint before installing them...as for the underside, if you can get the clips as originals instead of trying to use nuts, you'll save yourself plenty of aggrivation...because the gas tank is right in the way of the driver's side frame rail so getting a nut on a bolt requires moving the tank...
