Wheels to identify

13x5.5", 4.5" back spacing, 57mm center bore, 4x98 and two piece.

Looking to see if anyone recognizes them?

Yep... I do...

Those are the ONES! The round ones, all five of them...

HA!

Seriously, not in 30+ years have a seen a set of those! Where did you find them?

Craigslist

Post was 27 days old. I called the guy on a whim. Picking them up when I head north from SoCal on Monday. Guy selling them said they were on an 850 race car. Been sitting in his shed for 10 years or so. Figured some of you California guys might recognize them.

They look like one-off wheel centres to me? Maybe made by a machine shop?

They look cool!
