Drilling the holes shouldn't be too difficult if need be. Fitting the top takes very little ingenuity. If its fitted and has holes but the cab does not, simply fitting in place and drilling into the cab should be simple. But if the cab has dimples all the easier. Might be wise to mark from the inside once placed in position with a sharpie pen. A side angle drill would be the ticket then. I'd suggest you cherry out the top (slideing window) before final bolting down. Deal with rust and paint issues. But either way its a simple half hour on and off thing, even with just one person, though two is far easier. While fitting, before tightening the cab bolts, I'd make sure that the window/weatherstrip/cab all fit well and the doors close with an easy swing to completly closed and not hang up againsst the weatherstrip too tightly. Acess to all the bolts is good, the only hassel ones are dirrectly behind the driver seat, 3 I think, and they are not bad, just cramped and akward with the seat in place.
