70 duster front and rear screen removal.

There is a circular "cord" - the lock strip that runs from the bottom corners, up the sides and back to the opposite bottom corner. It comes completely out. The bottom section above the cowl "unlocks."

Hi demonic,
I didn’t realise the bottom section folded in.
Thanks a lot you guys for the speedy and informative replies, I will give it a go and see what happens.
I’ve done windscreens on mustangs(easy) roadrunners, and a 72 Dart (with no problems) but the duster is a tough one, wish me luck.
