I've got a 2003 supercab xlt with seat with the built in seatbelts. I want to swap for expedition or navigator seats. What do I do about the seatbelts?

 

Look under the carpet to see if you have belt mount nuts in the floor. If you do, get the belts, latches, from bolt to bolt, covers, everything from the donor truck.
Don't forget the trim panels, everything.
Then maybe it willl work.

If you do not have the mounting nuts under the carpet, well, you aren't gonna get seat belts in there easily. Someone will need to install (by welding) nuts for the mounts.

 

I'm hoping someone that has done this swap can give me a solid answer. Were some of the earlier super cabs bolted to the roof frame above the door? That's the only way I can see if it would work.

 

My 99 supercab bolts above the door.

 

I can't verify for you what's on your truck but I can tell you that I swapped a bench seat for buckets and a console and everything for the swap was already on the truck. There's no reason you can't look first to know what you need to do for a swap. BTW, I have a 99 standard cab truck.

 

Thank you, that's what I was wondering if some of the earlier trucks bolted above the door. @kd4gij does yours have the suicide doors?

 

Yes it does
