What fits>

Ok I know its been ask numerous times on what fits? I keep reading Cragar doesn't make Direct Fit SBP 5 X 4.0 Wheels, But they do. Summit list them and so does Cragars Web Site, I own a 71 Duster Front Disc brakes 4 piston calipers SBP and it does a damn good job of stopping the Duster along with the 8-3/4 rear SBP drums. Can anyone tell me with all the available wheel and tire combo why anyone would want to add the extra expense of changing to the larger bolt pattern?
I know its been ask before what wheel and tire fits a 71 Duster. What Id like to hear is form anyone running the SBP Direct Fit Cragars 15x6 3-3/8'' BS front 215x60 BFG TA Radials and Rear 15X7 4-1/8'' BS 235X60 BFG TA Radials
Just this combo and if there is any tire to fender clearance problems
Thanks PapaDuster
