partner 5000

Hi, fixing up a well used Partner 500 (1984-1988 version). I think it is missing 5052795-37 & 5052795-36 that connects the front handle to the base. 1) is 5052795-37 rubber or steel? Is it necessary? 2) What keeps 5052792-11 connected to the spring? If someone has close up pics of what it is...
