    bolt replacement

    I recently replaced the timing belt on my 2002 WRX sedan. During the install I stripped the bolt that goes into the tensioner into a bracket, which goes into the block. End result, I had to put in a new bracket (pn 13156AA062), which bolts into the block with two 8x55x20 bolts (pn 800708460).

    On to my problem: one or both of those bolts seemed to have backed themselves out of the block, resulting in a vibrating timing belt tensioner and a broken timing belt cover.

    Since I have the size (8x55x20, whatever that means) can I just go to a bolt supplier and buy a replacement instead of waiting for subaruparts or a dealer to fill my order? What about metal grade and thread sizing etc? I'd like to take care of this now and not have to wait 3-5 business days.

    I've had to do it before. Nothing wrong with a replacement bolt as long as it's the same size.

    I guess I'd like to make sure I know what I'm looking for, and where to find it. Since the two bolts are missing, all I have is that they are:
    8x55x20
    What do the numbers refer to? Do I need to concern myself with bolt quality numbers?

    update

    So I got the old bolts extracted with an extractor set and bought new ones at the dealer so I'm all set to go. Does anyone know the torque specs on these three bolts?
