Did you know 14 years ago when you posted this repair it would be useful in 2023? Doing the repair tonight on my '96 850 GLT. One problem, one of the circlips shot off the shaft into never land behind the work bench. Heading to hardware store tomorrow. Thanks again for the repair write up.

Thanks to all for this thread. Modified it to cold air only on daughters daily driver 850 GLT non-turbo. Drilled pilot hole in case and threaded screw in to hold hot flap closed. Note: just read mileage from ECU and its at 300,250. Goal was to reach 300K. Everything is gravy from here on!
