A/C Bypass Serpentine Belt

A/C Bypass Serpentine Belt
Hey, all.
My AC hasn't worked in forever, and I have decided to never fix it, because it's just not worth it. However, I was thinking it may be worthwhile to get the AC-less serpentine belt, for fuel economy.
I ran a search, but only found one thread that touched on this. The other person said he also bought a pulley. Am I correct in thinking that I also need to get a different pulley for the AC-less serpentine? Thanks for your help.

In my past experiences, (though none being on a Blazer) all I did was measured the diameter of the a/c pump pulley and subtracted that amount from the length of the stock belt. Then I relied on the patience of my good friend who works at the local parts store to pull a few belts in that range of length, cause this length is just a starting point (+/-) an inch or so. When you do find the correct belt, tear that belt # off the package and keep it in the glove box for future reference. (And to let the rest of us know!) Hope this is somewhat helpful!

@96Blazernut: I replied. Thanks for helping out.

I must have had a "brain-fart", I was thinking about by-passing my smog pump and was trying to base information on that experience. I reckon I should pay more attention from now on. Sorry.

I had one of the guys here ask me to post a couple pics of the A/C Bypass that I have. So I went to the storage building to go get it. This item bolts in the place of your A/C compressor. This will work on 96 and up 4.3's as the 95's have the compressor on the opposite side of the engine. This allows you to keep your current belt. I had bought this last year as my A/C compressor had some bad bearings and was locked up. I used it for a couple of months till I got a replacement compressor. This item is for sale too. $35 shipped This would be great on a mud buggy or any 4.3 that you dont care if the A/C works
Here are some pics.

If I can just get a little free cash, I might buy that from you.
I have a question, since you did try it out. Did you get any noticeable performance and/or fuel economy gains during the time you used it?
