What are the differences between the 2001 and the later 2001 2002.... models?

I know the block, tranny, interrior is a little different. My question lies with I am trying to figure out if my vin # matches up with what I have.



Blocks:
99-00 : Windsor (sp?)
01-04 : Romeo

Tranny:
pre99-01 : T5/T-45
mid01-04 : 3650

Since 2001 changed styles, I heard that a select few had the 3650 and the Windsor block. Is this true, and is it possible that another select few had the Romeo block with the T5/T-45?

 

or how about, how can I tell what block I have. I know what tranny I have. Any takers.
