This is one topic I've never seemed to get a firm grasp on. There'* all this talk about different lettered body styles (A, H, W). What do these mean? I haven't even been able to speculate as to what they could possibly mean? Little help?

mise well throw some more in there:
J
X
G
F

Good listing, Pat!

You saved us all a lot of trouble explaining.

Pat thank you the best explination of it ever! Good job!

It means cars of the same body have the same basic structure, and typically drivetrain. H-body for instance: Bonny, 88, and LeSabre. Look underneath, it'* the same. Pop the hood, looks the same in there, too.

Pat, you are a FREAK. You keep all this up, I'm gonna have you commited.

Relax, some people live up north where there is nothing to do, such as myself. Not everyone gets to live down south where its nice year round.

umm...ya im currnetly in NC....

It has been kinda chilly here lately. We got sleet Tuesday.
