    Tried to draw an image of the top bracket. this was the only thing I really had to modify to get it to fit. Just a small spacer .25 inch thick. I used a nut that was big enough to fit over the bolt.

    Interesting info George on the Toyota alternator, thanks for sharing. One thing you may want to check on the Toyota alternator is what direction the internal fan spins. I was at an alternator shop last week discussing this very subject with the guys there, and they were telling me that a possible reason for our over heating problems is the fan. If the blades face one way they drawn air in from the back of the alternator, and if the blades face the other direction they draw it in from the front and blow it across the stator. If the air is being drawn in from the rear it could be pulling in the heat from the headers, as they sit right above the alternator. The thing is you have to have the stator out of the casing to see what direction the fan blades are facing.

    Add it, and the part number for the Toyota 130 amp alternator too.

    I'll see if I can find a part number for the 130. I found several on ebay but didn't have a part number. As fare as the fan direction, I honestly didn't look at that. I can imagine that when the car is sitting at idle, that would make a difference.

    Here is the link for the 130amp. Toyota Corolla 130Amp High Output Alternator 1988 1991 | eBay

    Just a thought, anyone ever put a scoop under the alternator to divert air into the alternator? I've seen where people have talked about it, but has anyone done it?
