Find a truck or Burb in the bone yard and have them cut out the inboard mount bolts and the sheet metal risers that are welded to the floor.

Then you can have them welded in or you may even be able to use self taping sheet metal screws.

You may also be able to buy the part new in one of the body parts repair catalogs at your local parts stores.

 

when i put buckets in my truck it only had 2 holes on each side of the cab for the original bench seat i had to drill the rest of the holes out what i did was j b welded the new nuts to my cab and then used thread lock

 

thank you to both of you. i think i am gonna just do like doubt_me_now and bolt them in without welding anything. since i dont have a welder or ability to take is somewhere since the truck has no tags

 

well i got the bench out and like doubt_me_now said it only had the 2 holes, i think i might take the bracket of the bench and put a piece acrossed since there is a 2in diff from the outter and inner bolts
