OK I give up...How the H3LL did you bolt them down????????????

 

Most autoparts stores have universal type battery hold downs. Just need to find the ones that will work for your application. I bought a pair of mounts from O'Reilly's for my group 34 batteries.

...Universal Travis's garage mounts...I got those batts in the truck. With messing around and building brackets that didn't work then finally getting them in and mounted THEN rerouting every wire under the hood to get the cables to reach...You know what? The truck starts the same. I would recommend that anyone considering this mod to think again. Direct your energy towards something better like power increases or watching TV...I just hope it's worth the hassle come winter.

I always build mine out of 1" angle iron and have a strap across the top, then tie down with all tread or j bolts

 

I made a perimeter top plate with 3/4" angel iron and 2 "J" bolts made with threaded rod...It worked really well...Just a PITA relative to the benefit.
