Just wondering if anyone can decipher what the markings on the bottom of an R200 diff mean. The number 392 followed by a stamp or some kind and the number 724. I'm not sure what year Z the diff came out of.

Thanks.

probably doesn't mean much. ring gear is stamped with info on drive ratios etc. what you see is probably foundry markings or some such.

Makes sense to me. Thanks for responding.
