'65 Chrysler 300 Conv. Vent Windows
 

I'll need some help identifiying the vent windows I have in my car. When I bought the car all windows had fell and none were in operation, I sent all the electric motor to be repair and I started to install the glasses. The driver side worked very well but the problem came when I tried to install the passenger side window. The window fell off its tracks and was far from reaching the rear quarter glass ( about 1/4" short). I measure (dr side) from front leg of vent window, is touching the door front metal, to rear of vent window at cat wisker level and the I measure this at pass side and the result is almost 1/4 " shorter. I am suspicious that probably a vent window from another car, which is not exactly the same was installed in pass side. I read this numbers from this window "Mopar 2491352 and also R 13426, here is where I need your help the 1954-1966 Hollander Interchange shows a very different number V 3336-7 R&L. After that I wanted to know what number my dr side has, I thought I was going to find the same number that the Hollander gave me, that was not the case. Do somebody knows if the number given by Hollander must be on the vent window? Thank you for any help with this question.

Sounds like you have a different vent wing.

Here are the part numbers:

Vent Wing Glass - Clear: 2570968, 2570969
Vent Wing Glass - Tinted: 2570970, 2570971

Vent Wing Frame and Division Channel: 2491330, 2491331

Hope this helps. Try posting your issue on some of the C Body specific sites such as:

FWIW, your can find the vent wing units on eBay from time to time or you can try National Mopars. The Convertible part is different from the 2dr and 4dr part.

Thank you, Rexus31, for your information. Yes, look like I do not have the vent window that really belong to this car. I'll keep those parts number you gave me to check for the right one.
Thanks
