I am having trouble finding the components to add the extra alternator to my LBZ and also getting the correct size belt for the new configuration.

Any one got any clue as to the part numbers of the things I need to add the extra alternator?

Thanks,

) Second alt bracket: 97212348
2) Idler pulley: 97233352
3) Idler pulley bolt: 11515769
4) Alt upper mounting bolt: check with dealer
5) New Bracket to engine bolt same as above
6) Alt lower mounting to engine bolt 11516360
7) Alt 4 position connector (for use with OEM alternators only) 1530071*
8) Fusible link for alt output 15321209
9)Alternator (get same as your primary)
10) Belt 97300655 for dual 105, 97300657 for dual 145
*If you purchase an alternator with the new style 2 position connector, do not purchase this 4 position connector. Some of the newer alternators have a two pin connector. I am searching for the 2-pin connector, since my secondary alt has the two pin connector. I will post that when i find it.

GMDieselTech.com can help you with that. If i remember correctly the kit is around $600 for everything.

You can also try pit stop motor sports. He also has a kit for the second alt.

I got the part numbers for hotrent1 and bought them for about 140 from dealer and the alt. I got off ebay for 86 dollars off of a gm surplus dealer it was also given to me from hotrent1 and hey he even told me what wires you need to splice into it's real easy to do and the pia was putting on the belt

Looks like its definately cheaper to get it for $225 from the factory :o:
I also didn't order the 2nd alt. and i am regretting it.

Same Here.

I didnt realize it was an option until i was checking out this site over a year ago and i had already bought the truck. I definetly would have gotten duals, i have already replaced the alternator once now and waiting for it to crap out again.
