Installing rear window help?

Me and my friend need to put the back window back into his '49 dodge two door this weekend. I've heard they can be tricky, we have new rubber which 'should' be the right stuff, any tips on how to put this baby in without breaking it?

Thanks!

Never did a 49 Dodge but on the Merc. which is just rubber gasket no molding. I put the gasket on the window/ glass with a bit of Hi Tack to help hold it in place. Then a cord or heavy string in the body/roof side of the gasket, smitz it up with dish washing soap, get a buddy to help on the outside and pull the cord out ( you being on the inside ) as you work it along.
Sometimes a plastic "Bondo" spreader helps with the areas that don't want to co-operate.

Then when you get it 99% done with only one corner sticking out the slightest bit you tap it with the heel of your hand ever so lightly and watch it fucking break.
Ask me how I know.

 

Are you pulling the string out on the outside of the car, or the inside of the car?

 

"watch it break"

Well that's not very inspiring. What sealant or adhesive, Hi Tack or silicone or ???

 

I'm inside the car pulling the cord out.

 

I use a little "Hi Tack" (weather strip adheasive )just to hold the rubber on the glass and in place while working it in.

 

I just did a rubber channel style window on a '61. On HAMB, someone suggested using 3M product 08509. It worked excellent. I called 3M and they told me a few local places that sell it. Think I dialed: 877-MMM-CARS (877-666-2277)
