64 valiant/ 65 cuda door swap?

Hey guys,

Ive been cruising my local salvage yards for a passenger side door for my 65 cuda. According to the interchange book a 64 valiant door (one of which i found) will fit my 65 cuda, though it says the glass might need to be replaced. can anybody shed any more light on this? the new door shell is $150 so before I drop that I wanna be sure. And is it hard to install the windows?

Thanks

D
