Can also use #7 o rings from HomeDepot. Just scrape the old nasty rubber from the metal part of the seals and put the #7s in. Just got it done and no more boost leak. Oh, and make sure to lube it up good with dielectric grease (or 100% silicon grease)

I have done this a couple times on different TB's. Also remember to mark the springs so you can put them back together with the same tension.
