Sorry, I searched and cannot find the discussion that covered the conversion for swb non S 67/68 cars to S spec brakes. This can be done with early swb S brake calipers and rotors. But, the wider/longer S brake caliper bolt pattern requires upgrading the front and rear suspension components to include???

TT has done this. Bud, are you out there. (and Tom, are you racing in Phoenix this summer? I need pit crew experience.)

Thanks in advance. Shawn.

edit: for grammer and spelling this tyme.
