'67 Barracuda Bolt Pattern

I am going with a disc brake upgrade from SSBC on the front of my 67 cuda which has both the 5x4 and 5x4.5 pattern on the rotors . I am going to install centerline 17's on the car and going with the 5x4.5 pattern. For the back I am having a set of adapters made to convert it to 5x4.5 as well . Wheel adapters seem to be fine as long as you get the thick billet ones made and not the cheap china stuff
