Rear sliding window seal?

[Jrainman]

Ok so I saw this post last night , and I have a slider NIB that I got with my truck when I bought it . when I first took it out of the box and looked at it a couple months ago , I thought is was not the right window and figured wrong part bought by PO.

Then this morning I pulled it from the box and compared it to my OEM window and gasket. well it is correct .there was no company name on the box ,but on the glass it reads Tempered customs .

Now when I came back here to post my findings ,I looked at your pictures again and came to the conclusion

A) you have a 73-87 slider
B) you have a 73-87 gasket

I think the 73- 87 widow is larger So my money is on you are trying to install a 73-87 gasket on a 68-72 window.
