15x10 fitment on non-tubbed Duster

@72bluNblu Kind Sir, I am having an heck of a time trying to figure out if the Keystone's in 15x7 (3.75" bs) will fit in front without getting into the fender lip and still clear the ball joint.
I have just made a deal on a 1968 B-body 8.75" housing and I have several C-body housing's available to cut down so the 15X10 Keystone's 4.125" bs isn't a big deal. However, if I can't make the fronts work I might just have to scrap the Keystone idea due to having no options for backspace. I know the B-body housing won't work for the Keystone backspaces, it's just for 17's or 18's if I ever go that route.

Here's what we're working with:
1973 Duster. Rear wheel openings trimmed. Currently has 3" spring relocation and plans to do Dr. Diff's 1/2" relocation so I can use the OEM repro exhaust system and tips that I have. Can cut housing to custom length. Front wheel openings stock.

15x6 = 3.063" bs
15x7 = 3.75" bs
15x8 = 3.875" bs
15x10 = 4.125" bs
