'67 Overlander wheel help

[Goochagogo]

I've been fortunate to come into possession of 26" '67 AS. Overlander which of course has tandem axles. The problem is that I'm missing a wheel and having trouble locating a replacement. Initially I would just like to get her rolling so I can get her home. I don't want to spend a ton on a single wheel as I have already determined that I will be replacing the axles and hubs and will likely upgrade the wheels after the spindle size is determined. So I guess my question is if anybody knows where I might find an original 15" 6 lug (5.5 bolt pattern) wheel. If not are the originals hub-centric? I have located aftermarket wheels with the appropriate bolt pattern but the center hub opening is much bigger than the 3.5" of the originals which seem to fit snugly around the hub. As a Newby with his first Airstream any help would be appreciated.

Don't be concerned about the oversize center hole. I have run the aftermarket wheels for years.
If you know someone with a trailer ( don't forget horse trailers)with 6 bolt wheels maybe you can borrow one for a day or two.
Also some older chevy half ton 4x4 wheels are the proper bolt pattern, but you might have to slightly grind the center hole if your hub has little nubbins around the edge. The weight rating may not be right but they would get you home

Thanks Rick! My primary concern was the hub size. I will more than likely just pick up a used rim to get it home.
