Its probably off a mid 70s linclon mark 4 or a thunderbird,I hope you got the calipers with it as the core charge for them are expensive. I have had f**ds for a long time and never seen one on a late sixties to early seventies wagons,if there is such a animal I would like to have one for my 65 country squire. I think those rears have the same five inch wheel bolt pattern as chevy pickups.They are also very wide,lincolns had another disc rear that was in the granada bodied cars and were a little narrower and had leaf springs and parts are more avaliable for.
