Bottom pull derailleur.. under bottom bracket plastic guide ...shifters on downtube...easy peasy....and cable guides and cable stops. Otherwise it's some really bad Simplex or Huret thing and a full outer and zip ties.
I can make a shim for whatever tube size to derailleur no problem! Select a piece of tube bore it out to match seat tube OD then turn the outer down to match derailleur clamp size...easy peasy quickly lemon squeezy!
