OK, I have seen this done by people who have never done it. First thing you want to do is get two towels and roll them and rubber band them so you have a 3 inch diameter roll. These go on either side of the center rear pin. These are so you don't have to repaint the car.
Two guys hold the top while the THIRD guides the top. Remember there are 5 attachment points.

If you have not put the top on in a while then a little bit of vaseline or KY needs to be on the two above the windshield and the two by the doors. Having these turn easily and be in the correct rotation so that they fit down into the locking position will save you a lot of 4 letter words.
A 4th person small inside the cars is great. After you have done this a few times you will need fewer people.

Good luck , Go slow. Jack
