2008 DTS PERFORMANCE GONE (R.I.P.)
Not sure , but I do know that the limo's/ hearses have heavy duty brakes with six or eight lugs and other heavy duty upgrades. I would think the front clip would match up. will everything fit??? unknown. Might be different. I would start checking part numbers on axles and other main parts to see if there are any (show stopper ) part incompatibilities.
