Another Saginaw conversion question

I found the correct Saginaw pump, bracket, and hose off a 94 e150 with 5.8 at a junkyard in Memphis today. I got home and the ac compressor on my 87 5.0 doesn't bolt up the same way. My ac doesn't work anyway. Can I remove the compressor and add an idler pulley or something off a newer truck that will bolt to the Saginaw bracket? I know I may have to get a different belt to make it work. Any suggestions?

Pump mounted. Mounting holes lined up.

Well this ended up being kind of my experience throughout the day haha. Maybe it can help someone else doing the same. I ended up getting an ac compressor replacement idler pulley from o Reilly's for a 94 f150 with the 5.0. It may be the same for an 87. Not sure. Maybe mine had aftermarket ac and not factory installed but my ac compressor was mounted different that other accounts. Anyway, got it working. My 87 belt still worked.

The bolts for the AC compressor on the 1989 and older trucks are SAE (1/2" I think) and on the 1990 and newer they are metric (10mm)

It wasn't that the bolts were the wrong size. The mounting holes and bracket for the compressor were all wrong. They wouldn't come close to lining up. And the bracket for the stock power steering pump was much different.

IIRC the pulley on the sag pump is larger than the stock pulley. Verify that the spring tension pulley isn't rubbing on your upper radiator hose.

I don't know the belt routing for the 5.8, but could you have skipped the idler pulley and just gone with a shorter belt? On the 4.9 I think you can do that. My F150 4.9 came without A/C so I don't know for certain - I'm just swapping the stock bracket and pump for one sourced from a E150.

I thought about that but semi mocking it up with the stock belt it looked like the belt would hit the top of the water pump pulley twice. I don't know how to word that for it to make sense but it didn't look like it would work.

In 1987, they used what looks like an FS-6 series a/c compressor. For 1994, they had switched to the FS10 style compressor which used R134a instead of R12. Different mounting points too. So it looks like if you want a/c you need to convert to r134a.
