I can help, I just installed MB quarts in my 91 240. What I did, since the holes aren't even close enough to just drill new ones is this- Made adapters out of an old road sign. I used the oem speakers to make a pattern then cut them out and drilled two sets of holes, one for the stock mounting holes, the other for the holes on the speakers. You'll also need to use some spacers because the MB Quarts aren't as shallow as the stock speakers. I'd post some pics but I don't have a digicam right now. Hope this helps.
