Cal Tracs rear suspension or multi-link suspension kit?

Back in th 70s,all we streeters had was slapper bars and SS springs.
Back in the 70s, that's all we needed.
Back in the 70s we only had 275hp,340s

Now I have 420hp and wish I was back in the 70s.
I don't drag-race, so I'm OK with spinning out of the gate.
If I was looking for that kind of traction, I would build me some slapper-bars; from aluminum,I think. The kind that replace the factory axle-plates.
