Ouch, ouch, and ouch. But no, I wouldn't touch it unless you can get it for $200 and use it for parts.

The alignment, as you said, is going to be the killer. It's touch and go getting proper alignment without true equipment. While it can be done with careful measurement and string, it's probably not something you'll want to really be working on in your garage.

Anyway, if you insist on it, you can take measurements from your Electro-Metro as to the installed dimensions of the control arm mount and transfer them to your project.

You'll be able to make a jig that supports the control arms in the proper place and bolts onto the car somewhere (to eliminate variability) and weld in gussets and new support pieces around the supported control arms. When you're done like that, as long as your Electro-Metro has correct control arm alignment, the new project will as well.

The jig can be simple wood, or complex made from any number of materials, but needs to be strong enough to hold/support the control arms from moving in any direction, and hold their orientation both to each other and to the chassis of the car (hence the reason the jig needs to bolt to the car).

Hopefully, that was helpful moreso than a bunch of useless typing.

EDIT: Don't 3 cylinders sound funny with a fart can? LOL
