Ok, I have a 90Jimmy and I'm swapping out my powersteering pump. I had a really hard time with a rear support bracket that bolts to rear of pump with two bolts. It then bolts to first to bolts of exhaust manifold. Seems to be simply a support bracket. With it being extremely tight behind pump area it was a real pain in the a.. to get to those bolts and the bracket it self is big enough to where pump wnt dropout unless you take those bolts off the bracket. I know a guy with 89jimmy and his dosent have this setup. Just the three bolts in front. Anyone familiar with this and can I get away with not using this pain in the a.. bracket?
