Last weekend I found Mr. Gasket offset keys hanging on the wall of the Sevice Center Speed Shop in Lomita Ca. I needed an adjustable pivot ball for my Lakewood Scattershield which they had. They are for Chev V-8 crank gear but the keyway is the same width. I use a TCI Balencer which fits in the first key and crank gear fits on the second. 2 and 4 degree. 6 months ago I bought a 3 keyway set #8-1016 from Cloyes. right off the internet.
www.cloyes.com > high performance > page 11. Listed for the Late model but fit perfectly on my 1952 302 GMC. The Cam gear had the exact Cloyes # as my new set for the GMC which I purchased a few years back.
Cloyes is very helpful over the phone on their tech line. I originally called for offset keys and was told to use the #1018 set in my old engine. Just remember to dial in your cam with a degree wheel when you are done...I have found a Cloyes gear with the mark 1 tooth off which showed right at 15 degrees retarded.
Good Luck
