Brenda,
May try contacting Joe Neff, josefneff@comcast.net. Is a member of this club. I gave him the 3-piece wheel rims I had earlier this year, one being damaged.
I would not use the 3-piece rims myself, we had one come apart taxing. Although the blame could be attributed to me since I had anti-seized the allen bolts (they were Torqued) and inflated tires to 30 pounds instead of 20. I really think they should be able to handle that.
