NEED complete 1970 Dodge Dart V8 polygraphite front bushing set needed!...Where??

You will want the regular rubber for the lower control arm bushings...The problem with the poly lowers is that they tend to slide out when you try to press the LCA pivot shaft in. And also, if you have poly lower bushings, when you have them installed and tighten the nut, sometimes the bushing rotates, and messes it all up...So it is recommended to stay with oem style rubber for the LCA bushing, and PST doesn't sell them anymore because of all the related problems with poly lower bushings...So again, I would get the rubber bushings...
