Coming up short and drawing a blank on where to get documentation - info and ideas to find the info for the 351 catalytic converter part numbers. I remember back in the day, there was no difference to the 50 state and 49 state catalytic converters, they were the same part numbers, the only difference was under the hood emissions equipment.

The 1988 f150 has 2 of them. I'm speculating all of fords light truck / broncos and so forth are the same. Don't know about the ford passenger vehicles.
