Simplicity Broadmoor question

I have an issue with my pint sized Allis. I have a 1998 Simplicity Broadmoor with a 38" deck. I removed the deck and when I went to put it back on the spring attached to the belt tensioner pulley had come off. It is still attached to the tensioner pulley arm but I cannot figure out where to attach it to the second point. I looked at parts diagrams online and checked the manual but there was no help. I monkeyed around with it for an hour, normally it takes 2 minutes to put the deck back on. Where does the spring attach? Thanks for any help you may be able to provide.

I have three of them around somewhere. I think one is in a building setting on its rear with the front wheels in the air.  I think 14 or so years ago I removed the break drum from it. I will take my camera with me to the farm later today and if no one gets you the information before and the spring is still intact I will post a picture. The other two are blocked in to where it will take an act of congress to get them out.
