Wrap around sub frame connectors

Honestly, these look pretty nice to me. I started to build some sub-frame connectors (kind-of similar to those you have pictured), then I decided to buy some. I bought the US Car Tool connectors. They weld to the floor-boards. They are really nice high-quality sub-frame connectors. A very nice product IMHO. Of course matching all the floorboard contours requires more than a little massaging! PITA. If you have good (new) floor boards, they weld up ok. (I did.) But welding between the floorboards and the subframe connectors is tricky because the subframe connectors are much thicker than [brand new] floor boards. Also, If the floorboards are rusty: for get it. You need to replace those first. Oh, and the US Car Tool kind block the e-brake cable, so you need to work that issue! The ones you have pictured would probably work with the stock e-brake cable. (I could be wrong.) Also, I had to modify the rear-connections a bit. I didn't really care for the way the rear connections were done...

If I were to do it again I think I'd just make the a pair similar to these you have pictured;-)
