I agree with F Bill. When I was restoring my Jeep I ran into the same thing. The new repro casting was grainy and looked like something I didn't want to install. I didn't return it, I got more fulfillment in throwing it in the closest garbage can, where it belonged. I could see that the old one was worn in but not worn out. Sadly, I've had it out twice since then (due to other reasons as posted last year) and in 6,000 miles it looks to be just the same. No additional wear.
