BA, your not thinking outside the square enough. You say a NOS/2nd ECU and other parts for your truck are verging on unobtainium. Ford according to wiki and others are still making the engine for the moment, but your concern is the 'puter. Which if it's not EFI is resolvable by fitting a distributor, yet most EFI requires a ECU, so your looking a after-market ECU that's plug and play for ya truck. That's so not going to exist, the closest your going to get is an ECU capable of running any 1-8 cylinder four-stroke, but the wiring harness is going to be a DIY job.
Which means looking for something like a Megasquirt, but you're in America and the EPA hates them and California probably hates the others (Haltech, Motec, etc).
If you were driving a recent Subaru (90s-2010) the issue's a minor one as their parts are pretty interchangeable across models and years.
