Ford changed the passenger side alt/air pump bracket. I think around '93/4, whenever they did 3Gs on the trucks from the factory. Mine being an '88 uses the above picture style on the 302 for it short belted...and zero issue, been that way for 20 years easily. The '92 4.9 is routed the same
My pal has no air pump on his '89 with a '95 roller 351W. I forget how we short belted it, I will see if he has a pic handy and if so I will post it.

It looks to me like someone before you only removed the air pump pulley. The pump is still in place. You would have to remove the entire air pump assembly to use the bypass pulley and bracket.

Okay I bet you're right about that thing being the air thingamagig. So I got underneath it just now and tried to turn it. It turns freely about 1/4 turn, then not. This is by hand, And I would guess that seizing is why it was bypassed?
Gotta be honest here, I don't see how the pulley/bracket people are listing for me is a direct replacement for that thing. The bolt that holds it on seems closer to the center of the pulley on the thingamagig, than it does on the replacement.
Maybe it's just the orientation that is throwing me off? In the photos, the bolt for the bracket is to the left of center, whereas on the air thingamagig, it is beneath it, and seemingly by a shorter amount.
How confident is everyone that this is the correct part #? If anyone can vouch for it, I'll just order it. I think you've all helped me explore the alternatives enough to say that is the right next step.
I suppose I should also verify that my A/C delete was done correctly before assuming a standard belt will work, but I'll post that on another thread.

Okay after seeing this thread I think I've got it all in my head now:

Thanks everyone. Now I just need to find a source for the 68110!

About whether that bracket is correct, the listing I see says:
"This unit is a direct bolt-in when you eliminate the air pump. Uses standard serpentine belt. This part is for off-road/race use. Not for use in vehicles in pollution-controlled environments or for vehicles manufactured after 1995."
I have a '96.
Can anyone confirm what part number I need to replace the SMOG pump with a proper pulley/bracket? (96 5.8 F250 4wd)

You're misreading the listing. It says it's *not* for after 95. But it seems to go back to like the seventies. So, definitely not for just two years.
The only useful thing that came up when I searched was the link I showed above from this forum:

I guess I'll take a chance but real confirmation would be nice.

1996 F150/Bronco using EEC-V (OBD-II) with a 5.8L engine do not use an air pump. Ford must have used an idler so they would not have to stock a shorter belt and/or go back to the the earlier serpentine setup.
This belt routing diagram from a 1996 Bronco appears to confirm that theory:

I'm also pretty sure I have OBD I, but that is a question I've never been able to get a good answer to. (Why use the other labels if they just translate to OBDI and OBDII? Anyway....)
I'm not sure what the suggestion to "Google it" is for. What exactly is someone suggesting that I google?
So I'm just very confused here as to what AuroraGirl is saying, or the follow-up comments to it.

The diagram I posted and yours are the same. The text states Air Pump OR Idler. Simply stating why a 1996 truck with OBD-II is different...it does not use an air pump on 5.8L engines.
Obviously from your photos there is an air pump, but no pulley. Just to state the obvious...your truck is OBD-I. Therefore to fix your belt slipping off problem the most likely fix is using an idler puller assembly in place of the air pump.
End of conversation. Just trying to help.

1995 was the last year Mustangs had a 5L small block engine. 1996 and up they used a modular 4.6L. That idler assembly will definitely not fit those.
Why they don't list the F-Series, I have no idea
