The cab and bed will be a satin black. No fenders on it. I won't have to lean over them to work on it. Just sit in a chair. I am not really a fender kind of guy. Lol
Your lower alternator bolt without some bracket on the outside there is no support so the bolt is in single shear.
The alternator would need a U shaped bracket on the bottom then the bolt would be double shear and much stronger.
The bolt on the lower left is just for the adjustment of the belt. The alternator bolt will be tightened too. I have had them all tight and the alternator is very solid
The bracket material is 1/4 inch. It is rigid with the stiffener welded down the middle also. I have mounted alternators this way in the past on small blocks.
