Anyone know what size the throttle body bolts are on a 99-02 silverado? I need some longer ones for my plate kit so if anyone has any input on the matter I sure would appreciate it.

 

did you buy the plate kit new?
b/c it comes with the longer bolts.

 

bought it used off here

 

I just measured the stock studs for the throttle body. Its either a 5 or 6mm stud, 46mm or 1.8" long. The nut is a 10mm if that helps. I can get an exact thread measurement tomorrow. BTW my HSW plate came with allen head bolts, but I don't have a measurement for those. It would be easier/neater if you could use studs to mount thte plate.

 

Stock is a 6mm x 45 stud, 1.0 thread, but thats for my 06, not sure if its the same as your's.

 

id just call hsw, he should probably get you the ones you need for littlr to nothing

 

Thanks guys for the responses. I'm going to try my luck at the local bolt company and see what they can do for me, if not I'll give HSW a call. I'm just impatient and wanted them now, LOL.
