Denny, where else but Ebay. "Vintique Inc." brand.
Ebay You can find the tape in various thicknesses. I used 1/32" for both the window bottom track and the vent windows. The window track was the tightest fitting of the pieces and required minor blows with a rubber mallet to set the piece. The vent windows slide right on..one with a little bit of pressure needed and other was seemingly too loose and I did not have confidence it would stay in place. But, the next day it was locked in place. After oil is added to the tape, it gets very sticky over time. Great stuff...way better than the common vendors are selling (cork). Incidentally, I used ATF (non-synthetic) to activate the tape.
