When you find your wheel adapter be sure it allows for the fact that the stock Model A hub and drum is at two levels or you might end up watching you tire go down the street in front of you. Here is a post on a slightly different topic but it shows what I am talking about: http://www.jalopyjournal.com/forum/threads/40-ford-wheels-on-a-model-a.750368/#post-8330045 PS, I like the stock wire wheels or Kelsey's.
I suspect that you're going to have to have that combination custom made. I had I had a pair of adapters made to use 5 on 5-1/2 Kelsey wire wheels on trailer axle spindles with a 4 bolt pattern 10 years ago and it cost me $140 for the pair.
