I'm thinking about buying a used throttle body spacer(I know there is nothing to be gained, but I like the whistle) from a 99 Silverado. Will this fit my 04 throttle body or is there a difference between the two?

 

it depends if it came from the same motor that it is going to ...but i dont think there were any changes in engines from 1999-2004

 

Thanks, anyone else have any input on this?

 

99-04 have the same part number for the tbs. dont spend to much on this, but i have one also for the whistle sound.
