MOPAR things I learned the hard way..

1.LH thread studs exist
2. Most solid roller lifters don't drop in a sb w/o clearancing the block
3. Header bolts are into water jackets
4. Slant/sb/bb all have unique bell housings
5. Chrysler seemed to change something from one moder year to the next on every car they ever made.

Those are mine off the top of my head :)

Agree with LH thread. Day one of my first Mopar (April 1969), changing rear wheels. First lug nut on left side comes off no sweat, the other 4 will not come off. Bent a cross-style lug wrench with no sucess. Neighbor comes home from work (a Mopar guy) and stops over to see my new rude (62 Valiant) and I tell him my problem. Looks at me and says "Son, those are LH threads. See the "L" on the end of the stud?" The first one was a replaced stud - replaced with a RH stud. What were the odds of starting with the RH nut. Getting the 4 LH nuts off after cranking them super tight just added insult to injury. I think my neighbor left giggling and probably mumbling "dumbass kid" under his breath.
