It should not be very difficult. there is only one particle board to keep the speakers/back shelf in there plus everything else is cover in carpet for easy access. However i have to say.. when i had mine, i never thought it needed any strut bars in there. The trunk is very well done and very thick that takes care of any movement back there. I don't think the strut will add much to an already well made reinforced rear. My 0.02 cents.
