This is a brand new GM surplus IRS rear differential for a Cadillac. I believe it is a 2000-2003 CTS. It has a round 6 bolt driveshaft flange and it is a 3:73 ratio. Please check photos against your original unit and feel free to ask any questions. There is a sticker on the unit 3:73 GETRAG 21992547 0006450001206 and 00000NPM-00121. The aluminum housing looks identical to the other ones I have seen but this one is 3:73 and has the round driveline flange yoke. This pinion does not have the long pilot required for the 3 bolt driveline. This differential is a limited slip. I have heard of people using these in the Mazda Miata as an upgrade and in the Pontiac GTO's also. Buyer pays $40 shipping. Please see my other sales for more interesting and unusual items.
