Battery hold down bolts

If you could build a plastic cover to keep the grime off it and secure it properly it should be ok. I put mine in the trunk where it belongs.
Cleans up the engine compartment a bit to.

Here is my before and after battery install.  Found the gas can, hollowed it out and dropped in place.  The suitcase has my oil, tools, wiping rags, bottle opener and other clutter.
