Just wondering if anyone knows of somewhere we could find the gasket that goes on the top of the TB and connects the TB vacuum lines and IAC port section.....the gasket has been discontinued by GM for some idiotic reason considering the amounts of vehicles with these engines :fire  so now we are stuck with 3 spare TBs ALL with no gasket and one of which goes on the Grand Prix which can't run without one....

So yeah, would anyone know where we could possibly locate new ones of these, I would love to get 5 or so consider the amount of times we are messing with these things.....Not that it seems to matter but the number on the gasket is 83854.....

Try GP Sorensen - Fuel Injection Repair Kit # 96-3004

You could try to use a make your own gasket kit, found at pep boys or the like.
