The Original Holmes Hi-Speed Tow Cradles, are neat to have, but very hard to find. Did you see the ones I have, in my webshots albums. You would be less likely to damage what you are towing, if a Tow Cradle is used,with the proper attachments, instead of the old tow straps. It would be neat if you could find an original Holmes service body to go with the 515 wrecker crane.
