Hey Jacko, the bolts I had to remove were probably 8 mm, that uses a 18mm socket. These are the rear mounting bolts. Oh, I think your'e talking about front mounting bolts,,, my bad.. Not sure on the lug nuts, but it depends on wheel type.

Yeah - 2 different types of bolts. Why - No idea?
Guesses about FCA:
1. They shouldn't touch these bolts so we'll use 2 different. Add some loctite also.
2. FCA got a deal on them.
3. Make the owner's life difficult.
4. If they really want to remove the seats let them go buy the E sockets.
5. Let them buy the Mopar under seat storage.
5. Fiat - Italy - European - taking lessons from German engineering. (BMW MC owners know what I mean)
6. Serious answer?????????
BMW used red loctite on my tail frame bolts in rivnuts (think Ram bed rails) on my 2016 K1300S. They need to be removed to put the luggage rack on and the rivnuts were round. Don't know what Klause was thinking that day.
