15" Buick wheels from the '50s .........maybe also from the late '40s and early '60s. I used a pair of the Buick centers in Speedway Shells for my Buick. The Buick wheels have 5 x 5" bolt circle.

I used Buick, Olds centers with Ford centers in my 'dumped rim' high school biz.
Prototype Traction Masters were Black Pipe! (compression fit, what was gonna happen? Worked great.)
Every 'cool car' in the lot had dumped rims, mostly rears, some all 4. $$$$
Lotsa Buick wheels, $2 each. What, are we gonna run out? Dumped rims in black, $20 each.
Nostalgia......and, YES! I still collect 'em.
'55 Chevy front bumpers, too...in case they ever come back in style!

 

This won't answer your question directly, but, I had a similar problem. I had old Keystone 8" wide wheels. I cut out the centers and used centers from an old set of wheels that had riveted centers. Drilled out the rivets and knocked out the centers with a 2x4 and hammer. Knocking out the centers, and reversing the rim is how we did it almost 50 years ago.

 

I bought those speedway hoops and used my original centers from my 48 plymouth, they fit perfectly. They have 5 on 4 1/2

 

So you guys are having no issues with the Speedway hoops? I wanted to make some GM Rally wheels 8" with a 5.25 back space..

 

No issues in 3 years.

 

Hot tip: International pickup wheels thru the '50s had 5-on-4.5" pattern, were deeper than Fords, and 5" wide.
Center takes Ford cap, ('40-'48 pass. type) has identical 4 nubs internal.
I had an 8" Mustang rear in my '29 Hiboy, these wheels on rear were the 'hot setup'.

Oh, they also came in 16", thru the '40s. Same pattern, same hub cap nubs.

 

See what Marsh Racing Wheels has to offer..

 

I don't know what Stockton wheel has now but my buddy used to buy a lot hoops and I think a few centers from them.
