5 link?
Do you mean a 4 link with a PHR?
It's a couple months away but there will be a PHR story in the April issue about the seven main types of rear suspensions which are:
Parallel 4-link
Triangulated 4-link
3-link
Truckarm
Torque arm
IRS
Leaf Spring
Main differences are in cost and how much work they are to install. Do you mind a lot of fab work or are you looking for a bolt in deal?"A ship in port is safe, but that's not what ships are built for."

It's really REALLY had to design and fab your own rear suspension unless you're a mechanical engineer with a lot of skill. Sure, you could make something that works but it takes a lot of develpment to fab us a primo system.
Since you have a 1st gen fbody it would make more sense to go with something that has already been designed well like the Lateral Dynamics three-link, DSE four link or some other system engineered for 1st gens.
Sure, the system will cost you more on the front end but "time is money" and this would save you a TON of time trying to design your own system with the right geometry.. unless of course you have a lot of suspension theory knowledge.
It would seem that what you are looking for are geometry suggestions for designing your own system. right?
If so then there are certainly smarter people on this board that should be able to help you out."A ship in port is safe, but that's not what ships are built for."

Look at a Satchell Link, fairly esay to design and install. Good design for compromise to packaging issues.
