I'm looking for the size of screws that goes into the grab bar handle on my 2000 chevy camaro, there are 2 screws per handle they measure 2 1/4 inches long but I have no idea the diameter or where to get them, can someone help me, thanks.

 

You should be able to get what you need at a u-pull-it wrecking yard or maybe even a Chevy dealer I'm sure they used the same screws for quite a few years and probably several different vehicles.

 

I thought of that, in my area they have no camaro in stock in junk yards

 

Here's the illustration and description from the parts manual of what I think is the screw you're looking for. They are no longer available from GM online parts, but the description does give the size.
