Custom control arm fabrication wanted

[grendel]

This is beyond my bending skill.

I need an upper adjustable control arm made to fit the rear suspension cradle and knuckle of a 2012 Camaro.

Background:

We put a 2012 Camaro SS (LS3) IRS into a 1973 Camaro. It's 64" WMS to WMS.

Detroit Speed makes all adjustable links which I bought, except for the upper rear. They said stock's strong enough and strength's the only reason they make them.

With the rear at 64" WMS to WMS, I'd like to bring it in 1-2" per side. The DSE links have that much movement in their adjusters. The body is 70" wheel house to wheel house and we want more dish in the wheels. I also think tube would be stronger, even if Detroit Speed Engineering says it's ok.

Who the heck can make me a left and a right?

It's the upper link that looks like a Gull Wing. just under the coil spring in the pic. Art Morris makes an IRS based on this, but they claim their links are entirely different and thus unusable. It's also not adjustable.

I can free up the factory ones, if someone wanted to use them to create a jig.
