Engine Mount Bolts

[Moparbob]

Howdy,

Anyone know the length/grade/diameter and washer size of the main engine mount bolts is 73 spool type mount? Just the long ones that go all the way through with the locking nut. I don't have any and would just like to pick up a set.

Anyone know what size bolts I need for the engine mounts for a 1968 B model 440?

I know that the factory used a special 7/16 shaft bolt with a 11/16 or 3/4 hex on the end. The V8 cars used a longer bolt than the slant six cars did.  Those bolts featured 2 spades midway through to keep the bolt from spinning. I dont know if anyone is repopping them.
