I am looking for information on the proper shock cord rings to use on a Pawnee landing gear converted to towing. If you can help, I would love to talk to you. Doug Witkowski (512) 431-6579

Doug, the shock cord assembly varied on different models and serial numbers.. Take into consideration the max gross weight of the particular model and understand that is is how the different cord was determined. Shock cords were either 5/8 or 3/4 inch diameter. You can refer to page 40 of the piper PA25 parts manual for the exact part number.There was a serial number that held 3 cords, most only held 2 and I would never put three on a Pawnee used for towing only, it makes for a gear that has no cushion or stretch, like riding a bronco bull!I have installed several of these bungee cords on the Pawnee gear for a few planes. Trust me , it is a or can be a very dangerous ordeal. I will get a few pics out to you tomorrow showing my cord arrangement. Bob
