Fan clutch on my 99 D2 crapped out, so I figured I’d try one of the slightly beefier Hayden units, a 2781. It is too large in diameter to fit the fan properly, but I’ve seen numerous threads that describe the 2781 being a drop-in replacement (same for the 2991, which has the same diameter as the 2781). What am I missing here? I swear I did this swap on my other D2 years ago, and I don’t remember any challenge to it aside from getting the correct bolts.
