Will these parts fit my glenfield/marlin model 60?

[wolverine_173]

So i got a glenfield/marlin model 60 and when i bought it, it was missing the front trigger guard screw and nut.

So midwayusa has them but it says they are for the new style. How do i know if my gun is the old style or newer style?

Here are the parts
