Only one I've ever done myself was 2x3 thru floors with outriggers to mount a 8 point bar. I wish I had pics, but it was from a 86' Fox body Stang in the early 90's. These cars are actually very similar in this regard, and that design in my opinion is superior to bolt in's when using a bar/cage. I'm sure searching this site, or the net, will provide a bolt in option if your not doing a bar also.
