My adventures continue...

I was adjusting the alternator belt tension, and the bolt head snapped off. No big deal, at least I think. But after inspecting, I have a few questions

- what is the orientation of the striker plate that the adjustment bolt screws into? Should it be on top or bottom of the lock nut? Mine is on the bottom. I ask, because while tightening the adjustment bolt, it bent such that the longer part of the bolt below the striker plate interferes with the alternator fins that rotate behind the pulley. I took the A/C adjustment bolt and used it for the alternator and had the same result - both bent, but the head did not snap. I suspect the striker plate may need to be flipped, but it does not look like there is enough clearance from the water pump pulley.

- are the adjustment bolts for the alternator, A/C and P/S all interachangeable?

Thanks in advance.
