First, Hello everyone! Just joined and hope I can get help and give it when I can.
I am building a 1938 olds coupe Gasser that I have had sitting around for years. I am currently putting a rear in and had a couple around the garage.
I have been trying for a month now to identify it. It is a GM 8.2 with 11" cover. It is a 10 bolt with posi. The axle assembly number is what is stopping me. what I have is HM0422W1 BUT the problem is under the "HM" is a "E"??? I figured out that it was made in April 22...and it was first shift but that is it!!!!#$#$%^
