Having trouble finding wheels to fit DSE subframe

[Big Red]

I have a 69 Camaro with the DSE subframe. I plan on running 6 piston Wilwood brakes. I'm trying to get wheels to fit in the 17" diameter. I currently have Famosa Standard on the rear and I went to order the front wheels and was told that I can't run a 6 piston caliper with that wheel unless it's fat lip. I know that I can't run a 17" fat lip wheel on the DSE subframe.
I would like to stay with 17" wheels -- does anybody know if that's possible?

Thanks in advance for any help!
