Guess you will struggle without taking both seats out, I took one look at mine and thought it would be easier to undo two bolts and take the drivers seat out too!
Will take two minutes to take the seat out
both seats out, 2 people are needed really .... tilt cage back front feet up by dash, 1 person either side of car and carry it through, then push it back into place and give it a few firm taps to get it in nive and tightmark holes to drill ... remove cage and paint it tidy
... then refit
