Ok, ok. Very good news. I will probably use a disc brake kit that comes pre-drilled for 4X100 along with drums in the back drilled for the same. Hopefully that will work. Now the question is what size tires should I use? Will 205/35 fit on a 7.25" wide rim or do I need 215/35? Thanks again everybody!!

Oh, and the car mentioned above was not an SB. It was a 67' body with 71' standard chassis. The front beam was narrowed 3 inches.
