Year one 17 inch ralleys

What car are you considering putting these on because across the A-Body line, there are different wheel well sizes. When converting to LBP, the track width can change and become wider depending on how you do it. Going to the 73- up discs will widen the front track. Early b-body or A body 8-3/4 rears with bigger B and C Body brakes will make the rear track wider. These will sometimes require more positive offset (i.e. more backspacing) wheels. Cars like Dusters and Barracudas can get away with less offset in the rear, but not he 67-69 Darts. I needed a 17x8 with 5.25" BS to fit centered in the wheel well of my 69' with an a body 8-3/4 with C body drums and a 17x7 with 4.75 BS 73 and newer discs in the front.
