Water pump bolts

There is a spot on some engine where too long bolt will hit a cylinder wall. I Think that is lower bolt on left side of this engine where screw up happened. I know the bolts are 2 different lengths over there. These 2 on the right should be the same length but I'm not absolutely sure. Someone here has a 273 or 318 with cast iron water pump that they can take these bolts out of. I had one here up until last Friday afternoon. :(
The same rusted bolt condition can exist on the other side of the water pump. New water pump and 4 new bolts is probably the best plan.
Your change alternator bracket became Nightmare On Chrysler Street. Those movies usually have sequels. Yours doesn't have to. Dig in and kill the monster.
