81 K5 shell windows

[68camaro]

Greetings, brand new here so be gentle. My. 81 K5 has solid rear side windows and I’d rather have sliders.

My question is, are the windows the same size as normal truck windows or k5 specific? I don’t have hands on the 5 yet to measure, as it’s still at the previous owners getting work done.

Thanks in advance!!

You need the K5 slider windows. While I'm sure there have been some pickup toppers made over the years with a similar shape, I can guarantee the shape is still different and that they also don't seal up as well.
