how are the tops held on normally?? my front part ha 2 things that used the same latches that the front and there are 2 in the rear that kinda slide out and there is also 2 that slide out on the rear part of the roof on, i had a soft top, so i didnt know how to do anything, i kept the trim on the rear top part of the rollbar and put 2 screws thru the roof into the tub of the tracker, then filled the gap with bead backer and solar seal...the rear part isnt removable on mine
