Automatic transmission. I went by our gear shop, “geared up drivetrain” here in Nevada city California, grass Valley California, they said to take some pictures and bring them back in front and rear of the rear end and they could tell me if they could replace the ring and pinion. Thanks for the advice. Also, it is an automatic transmission first, second, Drive, I put a B and M shifter into it. The transmission is freshly rebuilt, so I hate to change that out. However, I think changing a Pinion and ring gear would cost about $800 here. Everything is so darn expensive in California . However, that sounds easier than obtaining a new rear end and welding the spring mounts on it. Still just digesting some of your responses, have to go to work today, I will check this out further. Any advice is welcome and very helpful. Thank you so much
