We are building a custom set of steel wheels. We have the centers and are looking for the outer rim. The rims are 15x8. We have purchased a set of custom made wheels and the stamping on the rim is "Made in USA 15x8.0 JJ Dot INTRO- 10-26 1999 Custom". We are looking to buy another set of these rims to fit our centers. If anyone knows who they are or where they are located, we could use your help. Does anyone know who makes INTRO rims? We believe these rims were made on 10-26 of 1999. We also believe there is a company that sells these wheels in the Denver metro. Thank you, stano
