The differences between 49-52 & 53-54 always made me wonder why they are lumped together too. Then I figured, what the heck, the front clips are interchangeable so I guess they are closely enough related AND they are so different from the cars that preceeded them and those that followed that it seems natural to combine the year groups. The name comes from a goofy pix of Mike Ness with a torque wrench. And it is called "tongue in cheek" or "satirical humor" . Geeeesh some folks REALLY need to turn down their "bitchaboutit" meter. ED PS- I spoke to your car and IT said " But I wanna be a Rockstar, baby!"
