Idler arm assembly torque?

[shoshone3]

Freshening up the steering, so I disassembled and greased the idler arm. Actually in very good shape, has 40k miles and 20 years. No rust, but the original grease was a bit hard. I am going to add a Zerk. My manual has no info that I can find concerning the torque of the nut holding the shaft in place to the housing. I should have counted threads when disassembling. My feeling is just snug should do. Anyone have better info?
