As far as i know, the only differences between a 99 and a 2000 Cobra are:
child seat anchors on the back, top of the seats
different pully tensioner (for 00 gts, but it might be the same one 99 Cobras get for the fix, not quite sure)
the rear valence says Cobra
and the "SVT" badge with "Cobra" underneath it on the back now says just "SVT"
also there is an 'inside the trunk' hatch release...
so the everything that will work on a 99 Cobra should work on a 2000, except maybe blowers (belt tensioner), but like i stated the belt tensioner change may have only applied to GTs, and may not apply to 99 Cobras with the fix....
if youre wondering where i got this info, it was from SVT when they sent me my certificate of authenticity... btw, my 99 is #962!

PS: dont forget, not only are the springs for a Cobra different, so are the rear shocks!
