Porterbuilt Extreme Dropmember Wheel Backspacing

[cshetsky601]

Im looking at ordering the Raceline hooligan wheels for my 67 c10 with extreme front drop member with standard length control arms, extreme rear member with trailing arms and outboard bags and with the bolt on body drop. Im wanting to run a 22x9 up front and a 24x10 outback. Im not really looking to narrow my rear end.
