1957 gmc 4104 window gasket needed desperatly

[Daddysmoney]

I have a 57 GMC with peninsula glass. well the right side rear window  window was leaking water,so  I toke it apart only to see the rubber molding was junk. After calling Luke at US Coach,he said that peninsula glass was the only people that had that gasket, dang it. to me all the curved window look the same.anyway. does anyone have this molding or know where I may find one. in big trouble here and hoping someone has some ideas.
I don't have  have time now for pics but this bus was my fathers baby. he has put a 6v92/730 allison in it and its 12 volt ground and other things.
  Also does anyone know where I can find the seal for the entry door up front. tired of stuffing towels
Thanks in Advance

Did you contact Motion Windows? They are the current owners of Pinninsula glass. Luke should have door seals if same as 4905.

Possibly Steele Rubber has something that will work?

I've found with the modern rubber you can just make stuff work..Unless you are restoring the bus to spec and spending 100-200k and want to get a mould done..

If there is a channel around the perimeter of the door, u might use 3/4" or 1" ID foam pipe insulation to seal.
Get the good stuff. UV resisting.

Daddy -

Are you talking about the rubber weatherstrip that surrounds the three-piece rear window on the very back of the coach?

If so, it's similar in cross-section to the front windshield weatherstrip.  You won't be able to obtain a new, one-piece replacement like OEM, but you might be able to find something by taking your old weatherstrip to an automotive glass shop that also specializes in HD trucks, etc.

FWIW & HTH. . .
