I have a 1978 Ford F250 351M. I need to know if I have all the right parts on the engine for passing smog.

Will my 1981 F100 Custom front Fenders,Hood, Grill,head lights all fit onto the 1988 F250 Custom? By looking at it all bolts look like they would line up but can't find any question like this online. Also the cab rear window, is that interchangeable with the F100s window? Going to replace doors on 250 from the 100 but I know those are going to switch over easy. (Both are 2WD)

1990 7.5L randomly shuts off while driving. If I let it set for a few minutes, it will fire right up and drive home. Usually, if I try to restart it right away, it just turns over and doesn't start, or briefly starts and immediately shuts off. I've replaced distributor cap, MAP sensor, fuel filter, and rotary button. Just ordered the infamous ignition control module to try it. Any other suggestions?

replaced EGR vale,tube and sensor,idle air control,throttle position sensor,vaccum solenoid,fuel pressure regulator,full tune up. will run when feathering the throttle, out of ideas

Ive put all tune up parts,then fuel filter,now vaccuum lines. Truck refuses to stay running
