I have an 88 3/4 Burb. Its stock except for the 33x12.50s that the PO put on it. (well there is that jungle gym of a homemade redneck brush guard/winch mount.) I plan to keep some type of large tires on it and they will not fit in the spare tire well. How difficult would it be to cut out the well and have a sunken tool box fabbed up with a flush lid? Also since two is always better than one, how would you re-route the gas filler neck so that I could put one on the other side?
