Replacement Battery with stock hold down?

I went to replace the battery in my MS6 last weekend and picked up a AutoCraft Gold 96R battery, but it was about 1" shorter than the stock battery so the hold down bracket didn't fit. Searching the forums for which batteries it seems that most people use size 35 batteries, but the online specs for them all seem to be ~1" taller than the stock battery (except the RedTop35 which is .5" shorter). Are there any batteries out there with the same height as the stock battery? If not, how does everyone modify their hold down bracket to fit the new battery?

Thanks!
