Question:

I have the rails for above the bed, will this kit work for what I need under the bed of the truck?

There are a couple of things to consider to determine the correct under bed frame brackets for your 1991 Ford F-250 long bed.

When it comes to rails there are 2 basic types out there: 10-bolt and 4-bolt rails. The 10-bolt rails will have mounting holes on the side flanges of the rails. The 4-bolt rails will only have holes on the top, center parts of the rails.

If you have the 10-bolt rails then you would need installation kit # RP30439. If you have 4-bolt rails you will need installation kit # RP30125.

There are no custom fit brackets that will fit your 1991 F-250 so you would need to use one of the universal kits depending on the style of rails you have.
