Unusual Front Sway Bar?, 73 1.7 Options

[Beach914]

I recently picked up another car to evaluate for my GT conversion. A 73 from north LA area. Has some major hell hole rust but longs and floor boards look good and survived the screw driver test so far. Jack point supports rotted but not through the longs. The jack points rotted because of dirt build up under the rockers. Rockers were rusty in the Jack point area only otherwise good. Floor boards behind seats are good and solid. No rust in the rear trunk and a minor spot in the front.

I've attached a couple of pictures of what I found when looking under the front end. This is a method of mounting that I have not seen on a 914 before. The sway bar is mounted on blocks that are through bolted to the tub area under the spare tire.
My thought is that this ain't going to stay and I'll pull it and straighten up the floor and weld up the holes. I'll have some pictures from the inside of this in a few days also.

Anyone seen this done before?
