Aftermarket wheels usually don't have the "pushed out" effect with just a standard spacer; they do have an optional spacer for Grant or Momo wheels that you can use to move the wheel outward by 1" or 2", but usually the only time you'd want that is on a '90-'93 car because the airbag wheel is "deeper" (extends farther out from the column) than the non-airbag wheels.
You say you've got one from an '86 on there right now - did you put it on there to replace the stock '87 wheel, or was that just what a prior owner had put on there?
Probably THE best stock non-airbag Fox wheel Ford ever came out with was the 3-spoke non-cruise wheel on the GT's and SVO's in '84 and '85. If you can find one in good condition with a leather-wrap, they're worth quite a bit of coin. There's usually at least a couple listed on eBay on any given day, but they vary in condition and can either be really cheap (like $50) or insanely expensive ($150+). Probably the best factory wheel you could ever hope to find for your car; IMO, the next-best thing would be a non-cruise '87-'89 wheel.
If you just want something different, I still have the stock non-cruise LX wheel from my '84 sitting in the closet, which you're MORE than welcome to have for shipping - looks kinda like a big "A" with a circle around it.
