Dash Removal in 72 Demon

I'm looking at purchasing a 72 Demon to go along with the 71 340 we have. I really am not a big fan of the non rallye dash in the 72's. I have a line on a complete rallye dash frame out of a 71 Demon. Is it possible to remove the dash frame with the windshield in place? I know there are mounting bolts along the front edge of the dash, just can't remember if the windshield has to come out to get at them...hard to tell looking at mine....

Thanks,

Mark
