Just bought a V-21 (74) which had been on the trailer since 1989. Along the line, someone decided the spreaders weren't really necessary, and did away with them and the mounts. If I could get you to run out to the back yard and get me a few measurements it'd be a big IOU in the favor dept. I need: overall tube length, ID and OD of the tube, the mount dimensions, and a description of the material used to fix the upper shroud to the spreader.
