I installed my own and it took me a couple days but I only worked on it after school.
After removing the old top I laid the new one on the frame to unwrinkle it.
I inserted the tension wires.
I aligned and stapled the top to the main rear frame hoop. I didn't use many staples in case I had to reposition it.
Note: When you install the fold over seam cover on the rear top loop make sure it folds over backwards so air won't unfold it when you drive.
I stretched the roof over the side window area and loosely attached the weatherstrip retainers along the side.
I loosely bolted the rear top retainer to the body with the top under it.
Focusing mainly on the rear half I proceeded to stretch and adjust the top to get the wrinkles out.
Once I got the top where I wanted I marked the top and retainer rails in relation to the top.
I removed the retainer rails and tacked the top to the retainer rails making sure the marks lined up.
I adjusted the top tension at the front windshield retainer so the top would stretch when lowered but not prevent the top from closing.
Lastly I continued to stretch the top and install the weather strip retainers along the sides.
Once I was comfortable I added the rest of the tacks where lacking, rechecked the fit and then trimmed the edges.
Hope it helps.
