Guys,
I want to make sure I know this correctly...
98-99 LS1 throttle body's are the same. 2000-01-02 TB's are the same? How can one tell them apart (assuming either some parts still exist, or none)?
thanks

 

The 98-99 TBs have a grey spring, 00-04 TBs have a blue spring and the truck TBs have an orange spring. The 98-99 and truck TBs have a half circle shaped bell crank on the throttle shaft were the throttle cable goes, the 00-04 TBs have a half egg shaped one.
