they are same as the t bird---i have 15 americans on my 66 they fit fine--my 57 has the original 66 wheels where the calipers came from and my 63 has a 67 disc set up using the 67 wheels--it does take 15 inch wheels but they look better on a 60-64 galaxie anyway---see if your mags will fit over them they may if they are 15inch
