I'm trying to find the part number for the 3g alternator that already has the dual vbelt pulleys for a 1990.. Is this it? https://m.ebay.com/itm/New-3G-Alter...-7-3-130-AMP-/401258487106?_mwBanner=1&_rdt=1 That back plug makes it look off to me.. I don't have my 6.9 today to look and see if this matches but if anyone has used it or could verify it for me it would be greatly appreciated. My old 1g is really dragging and making the belts screech in the mornings when its charging back up after starting it's pretty embarrassing. I know it's not my ac or power steering and after about 10 minutes it stops and all my belts are new and tight so it seems to be the most likely culprit. Figure it's a good excuse to do the 3g swap not really "losing" anything if it ends up being something else.
