7. Installation of the top is pretty easy with the supplied directions from Bestop, but it does take some time. The instructions recommend installing the top on a warm day and you should let the top sit in the sun for a little while so the fabric and vinyl will be flexible and easy to work with. The fabric, and especially the clear windows, are very sensitive to temperature. If it’s really cold outside, be very careful folding down windows, as they can become brittle and crack easily.
