Yo Dave - When I replaced my struts with Monroe Sensatrac's and put in the Eibach kit, I used Monroe Sensatrac's in the rear. I have no idea what part number we used, we just measured it against the Monroematic's. The result is a stiffer than avaerage rear. I'd have to add weight in the rear to get a smooth ride on the Highway but that's a small price to pay for stiffness.
