GM alternator installed

Jon,

Nice looking installation. Looks like a good economical alternative. What's the amp rating? What's the part number or application. Thanks.

Thanks Jon. Dan

I would like to amend my afore mentioned statement concerning the "outstanding customer service" at Tuffstuff. I had a QC question about the alt they sent me, specifically it would not send current through my system... When I reinstalled my 60 amp there was no problem. So after installing, reinstalling, ohming, etc.. I decided to send the tuff stuff unit back for testing... It's been a long time???... I have heard a few lame reasons why they havn't turned the unit around?.. They can't seem to communicate internally the status of the alt?.. They have yet to return three promised call backs??... I intend on letting them keep the alt and starting over... Any suggestions on an external 100 amp???.. The good news; My wife and I working as a team can now do an alt change on a Pantera "turn key to turn key" in about 8 minutes.. A P/N for a three wire 100 amp or equivlent that I might be able to use at my local parts store would be great?.. Thanks for any help or advice...
