they do bolt on with only minor adjustments for alignment. and maybe a little tilt fore or aft on the wind shield. only other consideration is how the latch style is. cjs have wo different striker styles, a round bolt style striker and a flat striker. that will affect your door latching. i was able to use flat doors on my yj, with a home made flat striker using a bolt, some washers for spacing, and a piece of flat steel cut and bent to the shape i wanted. i am not sure if you can make a round striker rod fit on a flat striker tub though as i never had a flat striker tub. probably can be done with some creativity though.
