OK - Bob at Vintage should be able to address that. But considering how the wheels/tires of the 427 SC cars still have to tuck inside the wheel openings (just barely) as compares to the open wheel well flares of the FIA to allow tire clearance, I'm not sure you will need that much additional backspace or the tires might fall well short of the edge of the fender flares. But I will be very surprised if Bob/vintage hasn't already dealt with this on ERAs several times over.
