Mitsubishi Repair: a/c tension pully, mitsubishi expo lrv, power stering

Question
The tension pully on my 92 Mitsubishi Expo LRV came off .  Without it the A/C and power stering do not work.  I have the replacement assembly part but I have no mounting bolt. What size , thread , and length of bolt do I need.  Also the the tension wheel has a blot that runs throgh it.  It is theaded on one end with a nut on one side of the wheel. On the other end the bolt has a horizonal-threaded hole.  Since I don't have the old part as I reference I have no idea what should go through this hole or how to mount the assembly. Can you help me by morning.

Answer
George,
I do not know the bolt size, thread space, or length specific to your tensioner pulley.  I would highly recommend you go to the dealership to get the bolts you need.  The bolts associated with the tensioner pulley are typically the mounting bolts that hold the assembly to the block, an adjusting bolt, and a lock bolt.  

Even if I knew the bolt dimensions, and you were to run out to your local hardware store to get them, store-bought bolts may have squared threads, while your block may take rounded threads.  Just have your VIN with you and go to the parts department at any Mitsubishi dealership and tell them the bolts you need.  They are not expensive even through the dealership.
Good luck!
