63' Lesabre lug spacing?

[kejonespequa]

Sorry if this has already been addressed, but I really have tried to find the answer.
I'm a High School Auto shop Teacher- We're currently building a 1963 LeSabre 2dr Sport Coupe HT. Every Lug Spacing resource we found, lists ony 1964 and up LeSabres.
Can someone please help us with a definative spec for our project.
Thanks

All fullsize Buicks were 5x5 bolt spacing from the mid 1930's to the mid 1980's. If you are looking for aftermarket wheels, the bigger problem is the hub diameter. I think '63 used a larger diameter hub than most modern wheels have.
