Looking for a throttle body spacer....

I have an l03 engine in my 88 trans am and was wondering if anyone makes a throttle body spacer for my stock throttle body. If there is one where can i get it from?

Re: Looking for a throttle body spacer....

Ok well just an update, I bought a throttle body spacer off ebay for 29.95 plus 12.95 shipping. When i install the spacer do i need to re configure my throttle linkages at all or will the car be ok? Just some newb questions since this is my first tbi car ive ever owned.

From what I've read you might have to find a way to "extend" your throttle cable or it will hold your throttle open just a little bit. also check your TV cable for adjustment. If that gets thrown off you'll have some problems.

The throttle body spacer came off a 1992 chevrolet Z71 pick-up with a 350 engine. He took it off before he sold it and never had any problems with it.
I was told that all you need to do is unbolt the TB unit, place the spacer under it and re tighten the bolts. Heres a pic from the auction. Anyone know if i will have to re adjust my throttle linkages at all?
