Hello Chris, I'm actually using 4" wide VW rims, they're easy to remove the centers (4 small stitch welds). I"ll build a jig, tack the centers and let a more experienced welder finish the job. Ballistic Fabrication, Tucson, Az provided the lazer cut centers. Send them a sketch they can make it, great people to work with....thanks for your interest looks like your project is on the roll.
