I don't know of a chart, I just had a parts man at NAPA one time tell me that 3076 was the Autolite for my '49 H. Then an old-timer tractor mechanic told me to use 3077 on older tractors. They are the same except for the bottom. The 3076 looks like a normal plug on the bottom, the 3077 has the long insulator and the probe part is tubular and comes parallel to the insulator and then turns in right near the end. These terms and descriptions are rough, I know. Anyway, I run them in '49 H and Cub, a '35 F12 and a '27 Regular, as well as several LA and LB IHC engines. Both the 3077 and 3076 use a 15/16 socket and my el-cheapo brand impact socket fits in all the heads without any difficulties. It is a tight fit between the pushrods on the LA's and LB's, but they will stretch to let it in there.
