The distrubutor hold down working as a substitute is cool--but I'd be afraid it will poke two fang holes in the battery when you go over a good speed bump..

..
The inner fender on my truck's passenger side is rotted enough so the battery tray was caving in towards the tire,and the battery would threaten to leap out when I was plowing and hitting snowbanks,or going over potholes and speed bumps...
I had to screw some sheet metal on it to keep it together,and I put some of that perforated strapping around the battery to make sure it wont just flop out of the oem hold down..
I wrapped the strapping with tape first, so it cant short out against the positive terminal..
The drivers side inner fender rotted away enough a few years ago,to the degree when one day I went to raise up my snow plow blade and nothing happened--thought the cable broke on the control valve to the joystick,but no--the control valve ,that was bolted to the inner fender,decided to pull the bolts right thru the fender and move,instead of the control valve piston moving..

..I ended up making a hasty repair by using some sheet metal from an old swimming pool to make a "patch" and secured it with nuts & bolts and drive screws..the whole nose is pretty roached now..
