    I purchased a rear window glass from LMC for my 74 c10. They had two options for windows, one for a 73-75 and 76-87. So I bought the window and rubber for my year. I tried and tried to get it to install but it seemed too the window was too big and would not fully seat in the truck.

    Am I missing something obvious here? I thought all the window sizes were the same. So why sell windows for different years?
    Any help or ideas would be appreciated.
    Thanks!

    According to the GM catalog they should be the same from 74-88. There is something diff about a 73 glass. I think it's the molding.
    There is 2 diff moldings, 1 with chrome and 1 w/o chrome reveal strip

    Do you happen to know of a place to buy a back glass that will work for my 74? I haven’t been able to find any info and LMC will not get back to me.

    Did you buy the installation tools as well? The little hook tool with the ball on the end and the rope installation tool are gold for this. The window should fit VERY tight and is an absolute nightmare to install without the right tools and a second set of hands. If you can get a local glass shop to install it for $100 or less you will be money ahead in my book.

    Are you using anything to “lube” the glass/rubber?

    Not to hijack OPs thread, but first attempt at removing the back window out of the 86 was not productive.
    It’s far tighter than the windshield which came out easily.
    Need to hit it with some soap water and an extra set of hands, but other tricks?

    I've removed lots of glass over the years stripping trucks for parts. I've never successfully installed a windshield or backglass myself. I just have local glass shop install after destroying several. Lube is definitely needed for removal and install.
