I have a craftsman lawn tractor model number 917.276816. On the lift assembly parts numbers 139865 and 139866 link arm lift part broke. On the parts list I don't see how or where the top of the arm lift attaches to the body of the frame. Did you have any instructions for replacing these parts? Thank you for any help you can give me.

Will this help: http://www.searspartsdirect.com/partsdirect/getSubComp.pd?modelNumber=917276816&productCategoryId=1509200&brandId=0247&brandDescription=CRAFTSMAN&modelName=TRACTOR&diagramPageId=00009&componentDescription=LIFT%20ASSEMBLY&documentId=P0606035&blt=06

Looks like there held in place with a hitch pin clip. Can't be that difficult to find the open hole.
