I am just planning ahead on the project and just thought it would be nice to have the factory original unit still in place. I am an assistant manager at a nation wide 5,000 plus store company and we do offer 1 year warranty remans, lifetime warranty remans, as well as new units on some applications. For the obvious reasons a new unit is not offered for the Z, but a lifetime reman is available. We changed suppliers for our reman electrical components about 2 years ago due to a high rate of failures. The new supplier has been much better quality but details are very vague about what actually gets replaced. Just thought it might be an interesting challenge to attempt but have no experience in rebuilding alternators. The commutator looks real nice, brushes still intact, bearings still free, but unit was covered in grime and the pulley pretty rusty. The last time this car was running according to the seller, as well as the inspection tag still on the window was 1996. 20 years of use and 20 years of sitting. Neither one a good option. Keep the helpful tips coming and I will continue to do some more research. Thanks again, John-Lugoff, SC. Thankful to the LORD for sparing us from the main fury of the hurricane and praying to the LORD for those who lost so much due to the storm.
