Types of 4-Link Suspensions

[69-er]

We have decided to go get rid of the leaf springs on the 69 Camaro and go with a 4-link setup. I've never examined one up close or installed one before.

I've seen "4-link" and "4-bar" systems. It looks like the 4 bar systems have equal length links while the 4 links are unequal. I understand unequal lengths are more desirable for wheel hop. This car won't be thrashed at the track, so the absolute best performance isn't necessary. Or is it?

Also, tire clearance is tight, width-wise, so I'm not too crazy on using a panhard bar. We really can't afford any side-to-side movement during suspension travel. Are there triangulated 4 links out there?

If anyone can point me in the right direction to get started on my rear suspension education, that would be great!
