Cobra IRS?

Yes, side to side but I meant the brackets rather than the bolts. Look at the lower control arm bolts for example. The force would come from the tire side, and all that's keeping the control arm from tearing that bolt off is the two pieces of metal on either side. I don't understand why they didn't have the "X" section take the control arm side-forces. Notice that the upper control arm and upper shock mounts are also designed that way. They didn't even bother with gussets to try and spread the load of the bracket.

That Bluemoon site looks like any other street rod suspension vendor. Flash over function, both products and website. Are those Global West control arms they sell? Or just tubular stock replacements for $600? Who knows? Who cares? It's shiny!

BTW that does look like a truck frame, and not any early car.

Yes, the setup I put in the convertible is the Heidt's Superide IRS. I believe it will drive and ride wonderfully, but it was a bit fabrication-intensive to put in. It looks like I'll be doing the DVS setup on a customer car in the near future. It is basically a set of brackets to adapt a late-model Cobra IRS to the 67-70 platform, along with a set of custom-length Koni coilovers. They've put it in a 65-66, but you have to flare the rear wheel wells (like SN65 did).

The pic that mdjay originally asked about is on p.74 of the May '05 issue of Mustang Monthly and is of a totally different unit than you see on the Blue Moon site. It appears to be based on the Cobra IRS, with a different tubular frame that picks up the forward leaf spring mounting locations and the rear frame rails. I emailed them about it a while back and have gotten no reply.
