Man you should see the lockers GM used in its late 90's trucks... The ones that suddenly go BANG! as they lock up. We had the joy of rebuilding the demo units at school. They look like a swiss watch inside! Seriously small small gears and such to make it work no wonder they had so many issues and trashed that set-up.
Yea Ford used them 2. A friend of mine had a 70ish 428 Cyclone (don't quote me) and every 3-4 burnouts he'd have to pull the clutch and replace the clutch disc because the shock springs were broke. It was a piece of crap.
