I knocked up a front spring box compressor tool using some small square tube, a long treaded rod and a couple of angle plates. Idea came from Mike Tylers video. I have had no luck finding details of a tool in the files. Not sure what other use.
I did try the "windlass" approach, lost some paint and really seamed sketchy.
