I just did this last week. I purchased the seals through Mach V. I believe they were $10.00. Very nice pieces. They replace the factory metal ring/rubber o-ring deal completely. Which is a good thing, because I completely buggered up one of the metal rings getting it out. I followed the faq, and didn't have any problems at all.

I had two of them, so I did replace the gaskets from the throttle body to I/C pipe, and the throttle body to intake manifold. You really could just use RTV in a pinch. Other than the two throttle shaft seals, that is all I replaced. I haven't pressure tested it since I put it back together, but it seems to be much better.

Joe --

Yeah, I think it was worth it. They completely replace the stock metal ring / O-ring combo. I think the outer edge of them are still metal, but they are completely enclosed with rubber and have grooves on the sides to help with sealing. I completely messed up one of the stock metal rings when trying to pry it out, so it was a good thing that they replaced it...!!!

As a side note, if you order online through them, it automatically will charge you 6.00 for shipping. They adjusted the shipping accordingly when I actually recieved them.
 

Do you think the $10 (plus shipping) MachV o-rings are worth it?
I have the #7 (1/2x3/8x1/16) o-rings at work (free).
