It is common to relocate the rear of the battery box a few inches further back and make a longer bottom for it. That'll help fit most any battery you want. Limiting factor is then opening in floor. So make a hinged or removable bottom and put the battery in from the bottom.
My 37 and 52 batteries are in the stock location and size. I took a measurement, went to a "battery place" and measure what they had till I found one with the dimensions I wanted and had all the reserve/amps and such that I determined suited my needs. I ended up with good one from Advance for the panel but choose a diehard for the 37. Its one of the easiest job you'll do on your truck.
