I put regular Goldie guards on mine which is originally a 1959 Shooting Star frame. The rear is straightforward, you just need the stays and bobbin spacers plus brackets, which are all available. The front was also easy, but I had to settle for just the lower stay, since the fork sliders only had provision for one stay. I later got a pair of sliders with two sets of mountings. The proper RGS items are different I believe.
