The local advance had a reman in stock,
"Driveworks" brand...case was the identical Delphi that I had in there as OEM. Installed the new unit at the campsite this morning and all is back to normal. Wouldn't be a road trip unless the truck broke down....LOL....
I've found that overall Advance is more like Napa in that they carry better quality stuff than AutoZone, hopefully this unit will be good. Was going to order a GM reman unit from Rock Auto but it would not be here until Thursday and we are running over to Pensacola tomorrow.
