Need help with Magnus install

[Onefast99gsx]

I just checked out Odyssey batteries and they have one that would probably be perfect. It's 680 crank amps. They're on ebay for about $69+shipping. It's about 3.75 wide which would probably be perfect. Hate to give up my good Optima. I'm gonna check tonight to see about going down with the battery on my 99 GSX to see if there is room for it. I will post on that. Yes, a reloc would let me keep my battery but more expense i think not to mention time, which i don't really have as i got too many irons in the fire already on this car.
