rear suspension design help needed

[wedged]

I'd like some opinions on how I should build the rear frame and suspension. I'm not trying to build the ultimate road course truck but I would like good handling. The easy way out is ladder bars and a panhard bar, but the handling is not great. I want to make a triangulated 4 link system and use urethane bushings instead of rod ends. If anyone with a suspension analiyzing program can help, I sure would appreciate it !

Here are the spec's for the space available:

tires bulge to bulge 33"
I have 2"x4" box tube on hand- max width O-O of frame rails 29" ?
wheel base 116"

The rear I will be using is a Dana 60

Mostly what I'm looking for is recommended link bar length and angles of the link bars, vertically and horizontally.

I'm figuring the lower bars should be parallel to the vehicle center line and the uppers angled from outboard on the axle tube to an inboard mounting point.
