i am looking into buying a stock t/b for my 98 t/a i was looking around on ebay and summit racing and on here and they all say they fit about any ls engine does it matter what it says on there? what is the stock t/b size? is there a recomendation where to pick up a cheap one at that you dont have to send a core in on it... i am looking for a decent throttle body for my ls6 intake

 

The size is the same 98-02, BUT the throttle cam is split into two groups by year. I believe it's 98-2000 and then 01-02, but don't quote me. Bo White could tell you.
