IRS D-Ring diff
just got some used parts off ebay for my 12th and i come across an IRS diff assemblely. i noticed one of the flanged bearings was sanded down so the D-ring could fit. from the looks of the axle it doesnt seem the previous owner had the ability to mill out a slot on the diff part to fit a d-ring and i dont recall IRS making dounut shaped diff rings.
just wonder if the sanding down the flanged bearing needed or i could get other type of bearing without the need of sanding?
