if your were to go with a group 31(won't fit well) just get a good quality (name brand) one.
group 31's are typically used in "heavy" trucks. i've talked several people to switch to group 65's over the 31's. they have the same amps but have a hell of alot better warranty. a typical 65 has at least a 72 month warranty, were as a 31 is only a 24 month. that right there is a easy choice for me to make.

Regardless of weather you go through the grief to install 31's(which I woundn't unless I had some really unusual demands) or go back with 65's try Centennial Batteries. These are not too common but worth looking for in the western US. These use the Delco Freedom technology- calcium / calcium instead of lead / antimony. They outgas very little and produce NO corrosion of terminals and truck parts. I have been using first the Freedom and then the Centennial batteries in my fleet since 1990 and no corrosion problems, good warranty and good performance. Check them out. Oh BTW another battery tip....the highes CCA's are not always the longest life. I use the mid level CCA's and get a longer life.

I used to use trojan group 31's in my lowriders, those were one of the best, took a TON of abuse, and kept on ticking. they dont make em anymore which sucks, cause when my current supply runs out I have to find a new batt [img]/ubbthreads/images/graemlins/mad.gif[/img](I still have twenty, I havent used)
