Dash Mounting Ideas

Do the older cars use the same type clips / nuts as 67/ later? If so you can reverse the clips and pay attention to screw length, and insert them from the bottom. This is the way my dash was installed.........after the windshield

In fact, I removed one dash frame in another car with the windshield installed, by using a small air grinder and cutoff wheel to slice through the clips. It was gutted, no radio/ glove box/ cluster or column, and no heater
