Well than buy the kit and rip in.after getting the kit and looking at the damage you will have a plan of attack.maybe even correct the cause of such a problem.Sorry but i have never seen a M-B wit a prob like that.sounds pretty straight foward if you have all equipment just a little time consuming maybe

P.S go to mbcoupes.com ask these guys ain't much they don't know about a 126 chassis M-B
