Having issue replacing drivebelt tension arm bolt
 

So I got a 1995 Gmc jimmy and the bolt that mounts the belt tension arm to the framework of the compressor/waterpump snapped. I cant find any info on this bolt to replace it.

Anybody know the specifications for this bolt or where it can be ordered online

Could be metric. Not sure thou but if you take the remainder to a good hardware store they should be able to figure it out.

Could be something like M12.

Maybe someone else changed that one and knows the dimension?
