So I see you were personally able to get the rears on. Looks like everyone used struts from the 89 280. I used the search and I was overwhelmed with the strut threads. I don't really see any easy successful fronts tho? I'm not a car guy so most of this is a foreign language to me.
Edit: Nevermind, upon reading all 3 pages and letting it sit and sink in I see the fronts and rears can both be done pretty easily by someone with more knowledge than me. I efffing love this site!!!
So I think I'm going to go with the monroe part # 71209 for the rear and for the front I'm going to grab the 73948. I'll make sure to get new rubbers and bellows too since that seems to be recommended, looks like for about $250 in parts I'll have brand new monroe struts all the way around. Might as well have him do brakes and tierods while he's got the wheels off since I'm saving about $600.
Wait, these have the rubbers and bellows!!!
