Old prefab sectional garage windows

I have an old prefab garage that currently has some very old rotten single panel windows in.

However, I’m looking to fit some new double glazed upvc windows. My concern is how do I go about screwing the frames in, if your not supposed to drill into the panels?

Hope someone has abit of wisdom for me TIA

    If it was me, I'd be looking at how the original was attached to the building. Maybe make a wood frame and then mount the UPVC in that, having first attached the wooden frame using whatever was used for the original.

    I think the wooden frame is fastened with M6/8 bolts. Is it possible to bolt upvc frame rather than doing a wooden frame for it to sit in?
