coil overs

Here's a thought... Go to a parts yard and find a 88 Accord or just about any modern car and have a good look at the structure around their upper strut mount.
To do something similar to an A-body would take strong fab skills but hey.. deleting the upper arm, upper ball joint, etc.. could happen.
In fact, if my memory serves correct, it was done to a second gen' B'cuda using Nissan parts, most everything from the firewall forward was Nissan except the body.
I don't think you want front wheel drive like that build had so keep in mind the caster angles are a lot different. Nearly opposite actually, so where a front wheel drive has the upper strut mount near its firewall, rear wheel drive would be much further forward.
