That's good, but no one seems to have any idea of the spring size, tension etc etc 2Second solution is to use steel tie wire with a washer at either end. But I have difficulty picturing this - how do you stop the wire from untwisting? And what length of wire do you start off with?? Both attempts I have had result in the twisted wire breaking before it takes up the slack and tightens the two baffles. 3. On another aircraft (production) I have seen a rod with both ends threaded that takes very small all steel lock nuts. This is the solution I want, but can't find any part numbers in my Lycoming parts book. Anyone have an idea where I might find them??

It's just a just a steel rod with a #4 lock nut on each end and a little off-set bend in the middle. When I go to the airport on Wednesday I'll see if I can find the old one to take some measurements for you if you're interested in making them yourself or can't find a part number. BTW this is probably an airframe part not a Lycoming part so you might check a Piper or Cessna parts book for one.

Try Intermountain Air at 800-433-9617. If they don't stock them, they'll know where to get them.

Cut the heads off from four 1 inch 4-40 screws. Peen a flat on the cut end of the screws. Drill a hole in the flat for safety wire. Connected each end of pre-measured length of safety wire to a screw. Insert a screw, with an adjustment nut already on screw, into hole in each baffle. Install all metal lock nut on end of each screw. Adjust for proper length and tighten nuts.

Not expensive and has worked fine for over 800 hours .
