Hi mate,
Give your local Caterpillar dealer a call and see if they have 8C-3629. It's a group 2 and by what I hear fits perfectly. I jus went and got one here today in Sydney. $140.89 + tax, but that's Aussie dollars. I've only ever heard great things about them and with 780 cca (cold cranking amps) they have some punch! Being Cat, I can only assume its good but time will tell.

Number 2 in the truck/agricultural/industrial on page 3.
Looks pretty good too, just a plain black battery, 3 caps, pos/neg terminal.
Now to get myself a 6 volt bettery tender and hopefully a solar panel to run it so this one doesn't die a slow and sulfated plates death like my last battery!
Cheers,
Ian.
