    Today I was putting together all the serpentine brackets and accessories before I put them on the engine and when I put the alternator on I realized that the plug prongs were different than my old ones. Is there a way I can rig this up for it to work right or do I need to find a new wire plug?

    get your electrical pliers out and find the new style plug, cut, connect, pinch, done.

    Just checked it out at Summit. With shipping its about the same price ($20), plus I already bought the one from GMpartsdirect. Then again I just ordered a reverse rotation clutch fan from summit so I wouldn't have had to pay the shipping from GMpartsdirect. Oh well, thanks for the info though.

    I'd recommend finding a donor vehicle from a junkyard and get everything from there. GM put serpentine systems in 88 and up trucks and 89 and up blazers and suburbans so find one of these. First off you'll need all new accessories including power steering, alternator, water pump, reverse flow fan, and AC compressor if you have one. However all of these can be purchased from any parts store, but it gets expensive so try to use what you can off the donor vehicle. What you'll need to find is the 2 brackets that bolt to each side of the front part of the engine as well as the bolts and the tensioner. I haven't put it in yet so I don't know what kinds of problems I'll run into but it looks pretty simple. The driver's side bracket has 5 bolts and the passenger side has 4. I'll probably have it put together in about 2 weeks. If you want, I'll take some pictures of the completed conversion and send it to you. Just send me a PM in a couple weeks and I'll hook you up.

    just go to any parts store. I got mine from advance auto. Didn't cost that much as I can remember. no sweat. I think there is a brown wire that is not needed. As far as I can remember it wasn't needed when I did mine.

    No, the heads are the same as far as the front mounting bolt holes go. So you don't need the heads from a donor vehicle, you can use your stock heads.
