Hook the front header first, then the rear corners. The first time I put
the top on my Rubi' I took a tiedown strap and tied a loop in the end.
Put a foot in the loop and hook the other end to the bow in the corner
and use that to pull the corner down so you can use both hands.After a
dozen times up and down it's not necessary. Also, you will have some
tugging of the top to get the rear panels aligned so that the windows go
in (rear and sides). Once they do I painted on a couple witness marks on
the tub for where the corners need to be for next time the top goes up.
Last thing: Watch the center bow over the drivers head. There is an FSB
on this. The saddles don't sit evenly on the rails, and will pop off to
one side. The cure for this is to pull down on the bod in the center and
bend it until the saddles fit correctly.

Is that Montana?  We still have three or four feet of snow in Colorado, and
everything exposed is covered with dirt, mud and road salt.  Whatever you
do, don't realign the windshield hinges or the body side door bottom hinge.
Once you do that, your hard doors will never fit again.
