Replacing undercarriage D41P-6

Looking for a guestamate on the time to replace a complete bottom. Only thing being re used is the pads. New rails,sprockets,idlers, top and bottom rollers and slack adjuster seals. Also new pad nuts and bolts. I know there too many variables but just saying everything came apart and went together as it should without any real issues. 2 people with proper equipment. Just ball park time wise. Thanks
