Bestop Soft Door Fix
We enjoy taking trips with the doors off, and we got a set of Bestop soft doors for rain. At highway speeds, the top of the door separates from the body by about two inches. The first time a semi passed me, I thought the doors were coming off! After much trial and error, I found a cheap, easy and effective fix.
I got a grommet kit and installed grommets in the top front corner of each door top. I tied a 1/16" cord to the frame of each door and threaded them through the grommet. When we're going to be traveling at highway speeds, I simply tie the strings together. I used a figure-eight-on-a-bight to make a loop in one string and I use a modified trucker's hitch to join them, so that tension is maintained. This fixed the problem.
