Front suspension Poly?

[SSDan]

I'm doing a Global West Cat 5 suspension on my 72 Chevelle, but I want to upgrade the other bushings in the front suspension. I need to know Polygraphite, rubber, Polyurethane...what should I use on the front??? I have the Delum(SP?) bushings in the A arms.

The only bushings left are the sta-bar bushings. Solid heims are best but polyurethane will work too.
