Advance Auto Moron: What car are they for?
Me: I have no idea I just need 6 Autolite 104s.
Moron: I can't sell them without knowing what car they're for.
Me: I have no clue what they're supposed to go in, I just need that specific plug.
Moron: You can't just swap spark plugs around, they're specific for the car.
Me: I know, I need them because they're the right heat range.
Moron: Your stock ones would be the right heat range.
Me: I understand that. The car isn't stock. Can you just entertain me and go find 6 Autolite 104s and sell them to me?
Moron: I'll try to find them, but you do understand we can't guarantee it will work and it won't hurt your engine.
Me: I'll take my chances.

I may be simplifying it, but that is nearly verbatim the argument I had. I hate chain parts store jockeys.
For future reference...any 4.0 V6 Ford Ranger from the mid 90's to the mid 00's...or something like that take 103/104's.

Just like an intercooler setup belt with a 3.0/3.1" on a GenIII with a full size core is a serp. belt for a V6 Isuzu Rodeo/Nissan Pathfinder.
