Does any one know what type cragar mags (old school) or similar brand 15 by 7 that fit on 1966 T-bird. Problem is the large front discs stop the wheels from bolting on (varous brands tried).

You can get some old school style wheels in larger diameters to clear large brakes. http://www.amazon.com/Cragar-Wheel-610P-Part-CRAGW-610P- 781245/dp/B00U05UECO/ref=sr_1_6? ie=UTF8&qid=1447568539&sr=8- 6&keywords=cragar+17+%22+wheels

Thanks Mark but I drive my T-bird every day and I have heard some people say they do not ride well on the larger wheels. Appreciate your input

There is a spacer available that is made for that bolt patent ,that will give you clearence.

Is the spacer for 15" or 17" wheel. How does the 17" ride? Are 15" by 7" wheel available?

The spacer is for the hub of the ft brake rotor,it doesn't affect the size of wheel.
