Hey BDCardinal...
I took that piece off this morning, but underneath was nothing to do with relieving the belt tension. Im really not sure what that bracket actually does here except for getting in the way lol

. BUT, here's what I found after some google'ing:
'99 Cobra belt tensioner? - SVTPerformance
Apparently some of our new '99 cobras with "The Fix" had the factory tensioner (1/2" drive equipped) swapped to this one (hole instead). An additional nut/bolt combo can thread into this hole and provide the leverage point needed to change the belt.
I went ahead and removed this (POS

) tensioner and will swap for a AZ / OEM Ford part with the 1/2" drive for next time.
Hope this helps the next '99 owner
