Hi Steve, I would go with the '64 Olds wheels myself ,but the '65 wheels look the part too. If I were to use the '65 wheels I would do them in chrome or maybe magnesium Either of these wheels would give you the 60's look your looking for. I am not familiar with this car in particular so, if it is a show car ,then I would say go with the 64 wheels. If it is a competition vehicle then maybe the '65 wheels in magnesium might be better. My 2 cents.
