1999 Silverado Seat bracket
 

I am putting two spec d bride style racing seats in my 1999 chevy silverado extended cab but the problem i am having is they don't make a seat bracket for my year truck cause the seat belt is built into the seat. Is there anyplace that you know of where i could buy one or is there any mods i could do to similar ones they sell. PLEASE HELP
Thanks,
Jake
