My rear wheels won't fit

[WH23G3G]

I just have been grabbing plain black steel wheels from other junkyard Mopars since my 73 no longer has any wheels at all. I got two 14 inch wheels for the front, because I want to use my original 14 inch wheel covers. But the two 14 inch wheels I got for the back won't go on. I've got the bolt pattern right but the brake drum interferes with the installation. I've got the 8.75 rear end with the big 11" finned brake drums. I've already got the new brake drums on, so I need a wheel that will fit. I want to continue to use the 14 inch so I can keep my original wheel covers. What kind of car do I need to get the wheel from so it will fit?
