I have a 94 lt1 trans am & am currently looking to replace my old bbk 58mm throttle with an AS&M 58mm but cannot find it anywhere. why are these so rare? Does anyone have the correct part number or link to where I can find one? thanks

Why do you want to replace it? Looks?

^Thanks & reason was that my old bbk throttle kept getting stuck and its dirty as **** no matter how many times I clean it its time to replace.

Although the AS&M piece is nice, you have to work with it to get your idle good.

You do know that the AS&M TB does not have a special "stay clean" feature......right?

The billet body is much, much easier to keep clean then a cast Tb that collects grime in every dimple and ridge. I have ran ported stockers, Summit/Professional Products cast aftermarket, and AS&M and the AS&M was a work of art.

Performance is obviously the same, and it needed the same IAC drill hole as the PP throttle body did, so is the dramatically higher price worth it just for looks? Depends who you ask.

I have a really nice one for sale.
I just had it rebuilt and repolished by AS&M.
