Seat adapters?

[Warthog]

Ok so I have some buckets from a later model two door. Fold forward ect. Issue is my mj is an 86 and I’m grabbing a set of those floor brackets from a guy on here. I know someone has had to come up with something to mate these two together. I just need a picture or description of how. I have a set of older buckets but they don’t fold forward. Plus these are in pristine shape! Any help would be awesome as I’ve studied this for a while and got nada! Peace to you and thanx in advance!
