Need info on susp. parts

[turbobuickman]

I will be putting in a full set of kirbans springs, some kyb's and airbags this spring and have a few questions about other parts i need for the instal. Does anyone have a part # for the rear spring isolators? And whats everyones advice as far as bushings go? How hard/ time consuming to replace them? which ones to use? im thinking ill stick with rubber since its a daily driver on rough roads. Can I get away with just doing some and not others? Any other tips? Also, does anyone have a template or sell a kit for boxing the lower control arms?

Thanks
Kyle

Ok, I found that HRpartsNstuff sells a boxing kit. How much for thier rear bushing kit and how often do they need to be greased?
