DIY all the way man! good stuff

watch this and looking for a to see what is around town. Saw ad, free garage door. Cool, looking at replacing wood sides of trailer and so door panels would be great. It had hardware too so got the torsion bar and it had the bearing plates. Buying plates with bearings and in it is expensive so free bearing plates plus a roller bar. Thinking of using some PVC pipe with those 3" to 1" reducer bushings since spring is 3". Unroll tarp but tuning in just enough to keep tension. I am going to use the cable and pullys. Pulley will extend beyond the sides so when pulled out it extends over the sides. Cable will also hold the sides from flapping. The conduit at the ends will be bent 90 to ensure tarp goes over the sides. I was going to just take the doors but remember seeing this and thought those bearing plates look like the bracket you had. All else fails can simply run a bar thru the mount and do what you did. Another idea was use old springs and mount to fenders. Use pvc or conduit and in center, pole holder. Make a conduit u shape over trailer so when you pull it the tarp extends over the load. DIY tarp arm

Nice job, looks like it should work for a while.
