Home Made Sub Frame Connectors

Here is mine but not bolt in and welded in through the floor

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.
