ok well i need to fix something else I just broke.
I was putting the alternator belt back on and I was working the tensioner bolt down and it STRIPPED THE THREADS OUT OF THE ALTERNATOR HOUSING. like the carburetor screw, it just broke. NOT EVEN TIGHT.
I guess I will be tapping and putting new threads in the alt.
On the slotted bracket? Just drill the alternator hole out and run a longer bolt all the way through and put a nut on the back side. Threads were probably shaky to start with. It's just aluminum.
