Another Gen III or "v" mid chassis bar...

I saw this on eBay. It's just like the Cusco, without the two extra arms.

I'm not sure that the back arms on the Cusco did any good, anyway, since is was held with the screws that fastened the two "parking cable" clips.

I don't particularly like the "welded" joints. It is probably made of 6061-T6 aluminum. the welds "anneal" the hardening at the welds.

It does, however, like the new welded steel bar, allow for less "torsional" resistance to prevent damage to the exhaust system tunnel rails.
