THE PORTAL HUB - Pinzgauers, Haflingers, Volvo 303s and more!

Hey all, first post. I'm getting a 710M and the group 27 batteries in it are toast, they've sat for yrs..... dead. I've seen group 31 batts mentioned, so do they fit??? Local farm supply store has both 27 and 31 for the same price. Naturally the group 31 is bigger and has more reserve and CCA.
Thanks,
Mike

I have Group 31s in my 710K.

Cool, that'll work., as long as I don't need to modify the truck to squeeze 'em in.
Thanks
