I hate to hurt your feelings but i didn't buy the aluminum houseing to save weight in my 3900 lb car. My orignal houseing was damaged and i wanted a new one. Finding good used 40 year old parts is not easy in my area. No local yards still have any. They have all gone late model. New one was a phone call away. As far as i know there are no brand new cast iron ones out there. I suspose i could have left the car tied up for weeks waitting to find one on ebag and hope it wasn't damaged when it got here. Houseing was not replaced to save 8 pounds it was replaced to get the car back on the road. I'm happy that you have access to a large supply of good used parts for your 40 year old mopar but not everyone does.
