I thought they wrer "cuisinart rims" in 1990, "sawblades" came out in 91. I had to replace one, found a supplier in Michigan,
but not cheap, over 300 with delivery.I wanted to keep it all stock and the only other I could fined were chrome at Mid America.
If you do find a set, Carcones , North of Toronto, does a very nice , econmical refinish. (140 per rim, picked up from your door, straightened, refinished to original and returned to your door)
