Ok so my truck bed has rust holes. I'm looking for a whole bed, can I buy a new bed and if so where.

 

I think he has a 65f100
Long or short?

 

It's a long bed F100, that would have been good information to share.

 

1964/66 F100/250 2WD & 1966 F100 4WD use the same Styleside 6 1/2' & 8' beds.

New complete beds haven't been available since 8/1966, so your only option is a used bed.

 

Ok is fabrication an option and if so what gauge steel is used?

 

Some have used beds from later model truck you may check into that.

 

If the holes are in the floor, replace the floor. There are also cross braces going from side to side that often rust. One can pretty easily fab up some kind of replacement floor or as was previously mentioned, cut one out of a newer truck and stitch it in.
