yes, the drains are the same 55.2-59, you can take off the kick panel air grills and see part of the setup, there are "deflectors" above the opening to keep the water from coming in those vents - run a garden hose into the top center cowl inlet vent and watch where the water comes out - fairly primitive design

you know that the windshields are available new? not too spendy, and if you have a shop obtain and install one they take the hit for breakage
