Need Help with rear axle dimensions

The flanges are standard 8.75 flanges same dimensions as all 8.75 rear axles, flanges are 1/4 inch thick bearings are standard size, I don't have backing plates as I had to cut the old tapered drums off with a plasma cutter, "rust welded together", but I did get everything safely off and have a great housing, bearings need replacing on the pinion and final drive chunck
