i need a new radiator really soon for my 87 325is, and remember hearing that the later radiators (starting around 1989-90 i think) will work with M50's. i have no plans to do a M50 swap anytime soon, but will be deffinately looking into it in a few years. the only reason i'm considering this is that the replacement i'm getting has a lifetime warranty, and i figure i could save $300 later on by doing this now.
