The International Cessna^® 170 Association

My 170B oil pressure gauge (Cessna part # 0411016-2 - 0 to 60 Psi range) is leaking. Cessna says the part is no longer available, and all of the regular sources turn up nothing. Is there another source for a similar gauge, or can they be repaired?

Scott (PN RN-2550) and Rochester (PN 10-00015) both make replacement gauges and are available from Aircraft Spruce. 877-477-7823
