Like Joe said, angle iron. The diesel in my 35-1 is mounted on angles bolted through the rails. 1600 hours and no issues. Another option is have a shop fabricate a channel and install it over the rails through bolted.
Look at stainless toggle bolts or Twist-Tee anchor bolts. If you drill the hole large, install one of those, hold it in place and refill the hole around the anchor bolt. However, that would require lifting the engine over the protruding bolt. Much easier putting a bolt into a thread hole than lifting an engine over a bolt. Not sure I would like a Heli-Coil or E-Z Lok here with the vibration. But it might work. -- Dennis C. Touche' 35-1 #83 Mandeville, LA
