Throttle Body Rebuild Kit

[1980_Cj7]

Having a little trouble finding a rebuild kit for a throttle body from an 89 Chevy C3500 with a 454. The Chevy dealer said it was discontinued. NAPA is showing one, but from the picture, it doesn't look right.

I don't understand where the gaskets with the one big hole would be used. This is a 2 barrel throttle body. I have to order it, and it is like $45, and I can't return it, so I'm trying to be sure. Next step is to start tearing this one apart and see if I find anything that looks like the parts in the picture I guess.

Anybody have any kit numbers or sources?[/img]

Nevermind, found it!

Took the tb apart. Just as I suspected, I didn't see anything in it that looked like the stuff in that NAPA kit.

Found one though. Autozone. GP-Sorensen 97-723. $35.99. This one looks like just the ticket. Of course, none of the stores anywhere around here have it in stock. I'll have to order it. No big deal, except that probably means two trips to the store. They usually won't order you one over the phone.
