I ran into a little trouble this afternoon. I'm so close to getting this GN 8.5" rear end into the El Camino but the Control arm bushings kicked my @$$. The rear end didn't come with them so I got some Poly ones from Jeggs. I tried one side with grease, heat, wd40, rubber mallet ect and only got it in half way. Is there a trade secret or would a shop have some type of hydraulic press? Now I did beet the hell out of this thing for 20 min. before I quit.
