Little help on this year one setup

[myrtle]

Looking for a little help on this wheel setup. Is this the 17x9? Any guess on the back spacing? Im assuming 275/40 on the rear tires, what about the fronts?
Anyone with better insight is welcome to help me out.
I took the pic from Mopars Invade the Strip this past April and never got around to meeting the owner to ask.

Thanks

It won't let me post any bigger pics. Id be willing to email the higher res pic if anyone is wiling to help. Thanks.

Here is a link

I didnt see a link, but he could have a b body rear in there with 1.5 offset springs.  A 9 inch will fit under there easy enough tho. Not sure about the back space for stock locations

Here is mine with stock suspension.
The wheels and the car are actually a little darker than the pictures. Pictures are uncorrected straight out of my phone.
Year One Part Number: MRWSL1

The challenger in your post has the darker 71 centers.
