The middle and rear side rails are quite different. You cannot substitute hydraulic rams for helper springs and have a power top. Didn't we just have this discussion a month ago?
I think we did , and I have yet to look at mine ,( top down ,boot on...)to see which I have...mine came manual from factory , but had motor , hoses hydraulics when I bought it , plus a bent rail the we welded/straightened/fixed...it COULD be the reason it got bent , if the manual top pieces didnt get changed out? I use it manually anyway , faster...
