I am in need of a set of brackets that attach to the floor under the front of the rear seat. They are the ones that the seat frame snaps into to keep it in place. My car is an ex racer and I have no idea why someone would remove these, but they are gone. Does anyone know of anybody that makes these or what can be done to replace them. I assume these are tack welded in place or are they riveted. Other than those the floors are in great shape and I don't want to replace them. Any help would be greatly appreciated!!!!
