OE stuff is metric, 10mmx65mm long, and the plates measure 30mm wide

For SAE, that would be approx 3/8 x 2.5" and 1 3/16 inches on the plates

I would box the arms for added stiffness as was done on the A bodies from 68-72

As an aside, I saw this on a car on ebay....not sure why they used a narrow bar off of a random car...maybe no G body donors around?

I would say that is a pretty sketchy set up with that sway bar and at some point will probably bend or tear the control arms being it is only bolted to the inside of the arms with spacers nonetheless.
