I have a set of bucket seat tracks and I am not sure what model they came off of. They came on a set of seats I bought and they attach to the seats just fine but the 4 I have must attach to another part of a seat track that attaches to the floor of the car. These are also slotted for a forward/rear adjustment. Does anyone have any ideas what model these go on?
I added some pics withe the tracks attached.

I have no idea ! Looks like something that would work with the super stock mounts
