Never had the first problem with Summit Racing and I've done business with them since Moby D-ick was a minnow.
As for Grant products....go to your local AutoZone/Advanced stores...check out the Grant wheels and the specialized adaptor kits that come specifically for YOUR application. One size kit doesn't fit all....a Caddy telescoping mount kit for a Grant wheel runs $75.00.
Like you said......Let the buyer BE AWARE!
