DRs and Steelies

I am going to be running 28-11.50-15 M/T ET Streets on my Demon. Just for cost savings I figured I would run the steel wheels. I asked my local go to Mopar guy if he had any to fit them. He said he can make some for me. $75 each wheel. Not a bad price IMO.

Does a 15x9/10 steel wheel not exist besides aftermarket? I guess i figured I could just nab some cop car wheels or something on that order and be good to go.

Or is it the fact that I still have small bolt pattern all the way around?

Any of you guys know for sure that these will fit with stock springs, spring location, and abody housing? I know I will find out soon enough once I get the funds to buy the wheels.
