I'm running 2008 wheels on my 66. I used 1.5" spacers on the fronts. You'll want to get the backspacing to match what will fit your car. 66 likes 4.75" backspacing, my 08 wheels were 6.12" back spacing, but you need to measure for your wheel, might be different. With the 1.5" spacers it simulates 4.62" backspacing, which is close enough.
