I need some help here. I bought a one inch offset rear end. The one I did have was a 3 inch offset. My firewall, motor plate has the honda sitting approximatley 2 inches to the left, not centered. When I try and install the rear end the jacobs ladder is past the birdcage and the left rear is too far out. Should I install a new firewall with the motor centered. The rear end is an older one with a key way that the hubs slide onto, so it appears that I cannot slide the birdcage out any farther, unless I cut the key way down to allow the birdcage to slide out. Any assistance is appreciated. Can't afford a new rear end right now. Thanks Dan.
