-- I can't find a stamping on the one with no ridge, but that wheel (15" X 10") was put on the car when it was built in 79 -80. The Guy, who built it, is a 76 year old Car Guy, My friend, who has buit several rods, and He bought the wheels, back then, and His word is as good as Gold. -- That takes Me back to My original question. -- The wheel with a ridge is a 15" X 7".
