I posted some time ago that I love HP exhausts manifolds over Headers in stock applications. Caught some flack on that comment. This week my friend had a serious PS Gear box leak. 1972 Plymouth Roadrunner 440. Removed Wheel, took 5 bolts off steering column, removed roll pin, pulled coupler out of gear box, took steering link end of Pitnam loose, took 3 bolts off steering gear box, took Exhaust loose on that side, and hoses loose. Lost some PS fluid. Then guess what? It came out with nothing more removed. Put new one in and on the road easy. Maybe should have taken Battery cable off battery for safety but did not need to. Good day we had.
