no way man, 48 is only way to go.
The distance roll bar to roll bar is approx 48 inches. perfect place to mount it. Its almost impossible to mount a 60 inch jack inside your jeep unless you plan on taking up alot of room. its wider than the jeep. I bought my 60 about 3 weeks ago still cant decide where to put it.
Take my advice, go with the 48, if not. buy the 48 and ill trade you my brand new never been used 60.
