73-76 A-Body Offset

Hello All,

I'm getting ready to convert my 74 Duster from Drum to Disc Front Brakes. What kinda, i.e., how much offset you guys running on your wheels? I'm currently running 15" Cragar SS with small bolt pattern and will be moving to 15" 4.5 bolt pattern. Is there a difference between the offset required for drums compared to disc or would they be the same?

Thanks.
