I purchased a set of black polygraphite bushings from energy suspension the other day for my stock bar (68 GTX)and have spent the last hour trying to get those @#$% things on. They slip on the bar (sans bracket) rather easily with the supplied lube, tight but still manageable. I just cannot get the bushings into the frame bracket once its there. In frustration, I took the bushings back off and tried to insert them into just the brackets - very tight and had much trouble getting them in. I did it, but had to really get ignorant with them using channellock pliers, and there's no way I can see doing that again while the bushings are on the bar. My brackets are not bent either, and I used plenty of lube. There's got to be someone out there who has done this before - maybe a trick or two you could pass along?
