L 48 Starter Bolts

[tmodel66]

I have lost my starter bolts.  Do I use bolts in all 3 holes to mount the starter?  Is the short bolts all the same or is this short bolt different?

The starter mounting uses two bolts - both have knurled shanks to accurately register the nose to the block. Don't forget the brace from the forward end of the armature case to the block.
