Ditto...  That is exactly what I wanted to build for mine but was too lazy to do.  I still don't see why they do not make the floor beams an integral part of the frame connectors.  With all the work it will take to install those, a pair of new beams would be nothing.

Those are cool and appears to be a really good product.  Does it say how thick the material is?

These look more like window dressing than really functional pieces despite what the ad says. For my money, if you've got a hardtop, convertible inner rockers and torque boxes will stiffen things up more than any other approach. Or do convertible inner rockers AND subframe connectors as long as the subframe connectors tie into more material further up on the front end and get back around the spring perches in the rear. I also think Maier's connectors are the best of that lot because they do that better than most anything else except for maybe what Mustang Steve and Gary Patrick have done with the Daze concept.
