Mirrors from Gran Torinos, Maverick, and Ranchero (the pedestals are different, but the mirrors, pivot mechanisms, and shape are the same). Same year Cougar mirrors are direct-fit (and the passenger side may even have remote controls you could incorporate into your car).
I know this because I bought the Cougar mirrors for my '71. I mounted the passenger side "remote" mirror, but haven't ran the remote cable yet.
The Scott Drake "objects in the mirror are closer than they appear" are nice and fit well - I put them on both mirrors to help with increased range of visibility. Your best bet on getting replacement glass is to have a glass shop cut some new mirrors if you don't want to go the repop route - I don't believe there are any OEM-style repop mirrors out there.
Hope this helps.
