57 Pontiac Battery Hold Down
 

I ordered a battery hold down from Ames for my 57 Star Chief. It came with 4 holes drilled into the sides of it. These were not factory holes. I called them with my concern and was told they drill all of them in house! When I asked why, he could not explain the reason. Anyone have an input to this?? The hold down fits tight against the side of the battery, so you couldn't get anything into the holes even if you wanted too.

The factory hold down has those holes. I think I still have a decent one as well as some parts to "assemble" one. Have some straps too, the 55-56 type & the '57 type.
Have any more photos of that hell rocket?

What would be the purpose of the holes??

Seems like I have seen cross bolts in there to either hold the battery down or hold it secure? Maybe for different applications?
Betcha anyone who knows is dead...
