I use 5 to 6 deg. postive as for toe in, with radials 1/8 - 1/16 if its darting around it needs postive lay the axle back you can do it your self if it has adj, 4 bar are hair pins.
CAMBER: No camber adjustment available on a drop (or straight) axle. (Unless you bend it in the middle, a risky proposition!)
CASTER: Yep, 6 to 7 degrees of caster just like Mike says.
TOE: I don't know how many degrees the toe should be, but like Dixie said 1/8". Measure from the center of one front tire to the center of the other front tire on the furthest rearward surface of the tire. Then measure from the center of one front tire to the center of the other front tire on the furthest forward surface of the tire. The DIFFERENCE should result in 1/8" narrower in front than in the rear. Does that make sense? It's going to be a little tough to measure with the fenders on your car unless you have a large caliper of sorts.
