I'm looking for some window weather stripping for a 1972 Avion LeGrande. The windows are Hehr brand but the old square corner version. The supply places, including the manufacturer, say they don't use that type anymore so they don't have it! So, what do I do now! Any ideas??? Help!? Thanks for any help offered! Oh yea!! Does anyone also know how to get their hands on a motor for the furnace in this old thing? Brand is Suburban, Model NT30, same situation, new motors are different sizes so no one carries it!! Whatever!!! How about any tricks to lube the sealed bearings in the old motor? Thanks!!
