Hello. Can anyone direct me as to where I might be able to purchase a used or new door latch for my 1953 Tri Pacer? My door pops open on every take off and landing and does not seem to catch when shut. The latch mechanism inside the door has been messed up by someone in the past and there is even a coat hanger wire for the unlock knob. The door lock does not work either. Someone told me the "cabin door latch" in Wag-Areo, item # 1-2594 on page 43 would work. Is this correct? Thanks!
