Signed up in Sept. when I got my TB, but had an issue w/ the activation so just lurked till I got my lift done (relatively done). With all the info here and at GMT360, I haven't had any issues I couldn't find an answer to. Thanks for all the tech info.
2004 TB EXT w/ 5.3, G80, Mark's 3" body lift and 3" suspension lift. Still lots to do including 4.56s and bumpers (prob Barton's). Its a toy that can carry the whole family so I'm not too worried w/ cosmetics.
