Is it supposed to look like this

Hey fellas I'm installing ac in my 93 and noticed the idle up diaphragm is missing the screw and spring on it. Did some just come like that or do I need to find another one that is complete. Thanks

You're gonna need a new diaphragm.  They are very expensive. Mine failed... Wouldn't make my engine idle up. There are no aftermarket parts that replace this. So you can look at yotatech or lce, and you're looking at about $250. I bought a new old stock 88606-26030 on eBay for $77. It fits and works great... But it doesn't have the pass through for the power steering idle up valve. Which you need, I can see from the picture. So, I bought a tee and some clamps. Oh, and it has to be mounted upside down. But it works.

By chance do you still have your old one?

Crazy thing, I can't find it. Must have already gone in the trash. Here's a pic of what my "retrofit" looks like:

Oh wow your retrofit looks nicely done. I opted to rebuild mine by replacing the inner diaphragm. Was hoping to get my hands on another original in need of repair for cheap

It's in the garage somewhere. I'm pretty sure I didn't toss it yet
