Dual 145 amp alternators

[quackershack]

Trying to put dual 145s of my 06 lbz. I have the brackets and the wires off my 02 but this is where it gets ugly. I cant seem to find a long enough belt, and the wire that plugs into the pcm doesnt have the right end on it. Im sure im not the first to do this, so could someone please enlighten me. Ive tried to google it and come up empty. Any help would be wonderful. Thanks, Jeff.

I would suggest visiting your local GM dealer's parts counter. Have them bring up the illustrated parts breakdown on their computer screen for the components in question. You can help to point out what parts you need, and they should be able to order them for you. Apparently, there are a few differences between the LB7 and the LBZ dual alternator components.
