my buddy gets me these for free. i brought one over yesterday for me and i want to know if anyone has used them, and how you modified your bracket to fit it. its the same width, but a few insches longer than a regular battery.

i use the yellow optima battery they are great. no modification was needed for me. just used the factory clamp. in the factory location.

you have the commercial one? its a bit longer. and has no where to clamp down at the bottom.

you'll need to change to a top clamping style.. you need to use a clamp that goes on top of the battery and then the bolts are J hooks that hook on the side of the battery tray as there tighten down

I found this one at http://www.wranglernw.com/commerce/ItemDetail.asp?ItemNo=34%2D942

I wish I had a friend that could get me a couple of them....

I run that group 31 yellow top. It is longer and taller! In my 91, the factory battery tray would not work. The posts hit the hood. I took a piece of 1/8 plate and welded it to the inner fender. I also welded a 8" piece of 3/4 angle iron to the bottom for support that rests on the inner panel. You will love that battery. I would recommend it to anyone.

I run a group 31 also, however I've got a '79. Great battery, lots of reserve!!! The tray mod was easy... just notched the vertical support next to the rad to let the end cell hang off the edge. Took about 2 minutes with the grinder and some epoxy paint. The hood is close but cleared fine.

I got a D31. It's sweet. IIRC, i think there was a guy on ebay who made billet trays for the D31. They were pricy though, like over $100.
I made my own tray & hold down, i had to anyway because of the tilt front clip the battery needed re-located.
