I'm the Wiz, and nobody beats me!
Sometimes finding the right stand can be a real PITA. Looking at this parts page it seems the 27" and 26" lightweights have a different stand. The length and bends are critical. The one for the Manta may be a closer match. Here's the 1962 parts page but like I said, the numbers were stamped on the stands at a later time.
