Use 6" Bundt Wheel On Spare?

[al76slc]

Just noticed one of my new (used) Bundt wheels is 6" wide. All of the others are proper 6-1/2". I'll be using standard 205/70x14 tires.
Can I use the 6" wheel for my spare with one of the old 205/70x14 tires? Will the standard lug nuts work?

BTW, any good sources for lug nuts?

I just learned that I had the wrong lug nuts for my spare tire on the 99 sl500 that I bought...when I had a flat! (talk about bad timing). I got the correct nuts from the dealer for about 18 bucks for the set. You can probably go to a junkyard and find the right lugs, but why not just get the right ones?
