Found my dads original 1971 duster!

I don't think you have to pull windshield. You can pull instrument cluster and glove box and reach everything. Pulling steering column frees up a lot of room too. If you pull instrument cluster push towels up under dash frame keep cluster from scratching frame.

Already pulled the windshield successfully! Saved glass and gasket. I’ve tried taking just the rallye dash out, but it seems like it will break if I try any more. Plus the supposed builder has a lot of stuff not plugged in that I can see when I lay and look underneath. He also has everything done wrong or forced into place. None of the vents will slide etc. Looks like I’ll have to make sure everything is redone properly at this point
