Yep, did them one at a time, utilized a floor jack.
I would suggest spraying the old crusty existing mount bolts down now with penetrating oil. If you can spray down the bolt head from inside the cab too, it may soak down and run onto the shank of the bolt, that's where mine were siezed up.
If yours are like mine the drivers side wasn't bad, passenger side was rusted solid. Had to use an air chisel to hammer it loose from it's 45 year home.
I ingested my yearly supply of iron :-)
Good luck, let us know how it goes.
