I used the original hold down with no problem. It's a larger rectangle than the optima battery (mine is a red top) . Since the battery hold down is held by a rectangular frame on TOP of the battery, and the terminals are now on TOP instead of the side ....the '+' terminal is kinda CLOSE to grounding out on the hold down's recatangular frame.
I arranged mine so that the battery + terminal is pushed about 1" away from the hold down frame, so that it won't ground out, I have had no problems whatsoever.
It's really nice to paint and clean that battery tray and be DONE with no more acid leaks.
Those of you with an Optima battery and a small block....since the battery is smaller, can you get it in and out without having to unbolt and move the coolant reservoir?
I was able unbolt the tank (hoses connected) ....and pull the whole mess over towards the valve covers. I could them turn the battery, and lift the battery out.
I have a ZZ SBC 350 crate engine though ....possibly a slightly different profile.
I would not want to try and accidentally pull a hose off a tank or worse yet, crack a fitting going into the heater core. Unbolting the tank is certainly the lesser of those evils IMHO.
