Little blue threadlocker maybe?Finally got my 120amp alternator installed. Clearanced the brackets and the timing cover for the larger alternator to fit.
As I was putting it back together for the last time, the upper bolt on the aluminum bracket, went loose...oof I think the threads gave out on the block.
I just left it there. Need to keep an eye on it to make sure the bolt doesn't back out.
For now, there are plenty of bolts holding the alternator in.
