Hey Oly, I was talking with a friend who also has a 1968 convertible. He is more of a grunt mechanic and has no patience. That said, I asked him about his converting from a manual top to a power top. He said that besides the obvious parts like pump, cylinders, hoses, wiring, you need a power top frame or at least the rear parts that connect with the power mechanism. His car has the top frame off and needs everything so he figured why not convert. After dealing with problems trying to find the top frame parts, he is convinced the manual top is easier and simpler to have. The power top parts are very expensive and they also tend to fail at the worst time. [I can vouch for that] He says since manual top parts are practically throw away items, he is going to fix and keep the manual top. Just thought you would like another opinion.
