Thoughts on fitment? '92 Caprice

Hey guys, looking for an informed opinion on whether or not this will work on my '92 Caprice wagon.

I'm looking at the 15x8, 5x5 with a 4.75" backspace, and I plan on putting P225/75R15 tires back on it. They offer a 5" backspace, but not for the 5x5 bolt pattern. I'm on a tight budget, so that makes my wheel options really slim!

Actually, I'm open to the sizes to go with the new 8" width. Something no taller than stock, but wider?
