Default does a 1990 have addition a/c braces????

I'm curious, does a 1990 have additional braces going to the a/c bracket from the exhaust manifolds? If they do can someone post a detailed picture of them? Also does the alternator & smog pump have4 anything like this?

I want to get my a/c going again but not sure if the car ever had these types of braces.

Indeed, if the exhaust manifold has a stud instead of a bolt in that position then the round bracket (with flattened ends) is missing.

Here you can see the stock alternator brace connecting to the back of the alt. (the bigger alt. is CS-144, which I installed):



And later I had the brace modified to fit with the CS-144 alt, because the attachement is different, but this pic is a bit clearer than the one above:

thanks yorcci & rodj ....... seems my car is missing all of them, if I can't find the originals I will probably have to fabricate some. yet another setback LOL. Maybe I can buy some from other GM makes and modify them to work or something.
