Have a two part question. 1) What is this spring (please see first pic) It was in a box of parts of a 1977 B100 that was overhauled and the owner passed away before putting the engine back on the tractor. I had to reassemble the pto but I have all the parts for it. 2) Where can I get some speed clips? These are used for attaching wiring to the tractor. (please see second pic) Thanks, Todd, New Guy
