Nathan - Did some research and found that there are only two possible calibration parts list numbers for your truck given the 2wd, 1986 302 EFI, and manual transmission.
As you'll see, 492 is for a truck with a manual transmission, and 494 is for a truck with a "TSOD" transmission. I don't know what transmission that is as, while there are other references to it in the catalog, I don't find a description of it. And, in the
Transmission Code listing there is no TSOD. But there is a T5OD.
So, what is your truck's transmission code on the certification label?
