I just pulled the rear end on my 37,1/2 ton. I have not posted them yet in my photobucket but will try to post them by tomorrow. I will take some pics with some measurements tomorrow also if that can help you or anynoe else. I do have pics I took with the perches off and spring measurements also. They will be in the folder "Chevy teardown" you may have to wade through more than a few pages to find picks you want to see. If you have any measurement requests I will be glad to help you out since the garage is only a few feet away and everything is getting taken apart and inspected whether I am going to re-install it or not. I do have some close up pics posted with the cover removed of the rear end gears. Also there are pics posted of the backing plates and brakes.
