Answers.Text: I'm not to sure, It looks like it could be 553(a) or 553(b) but not 553(c), They stopped using 553(a) in 2009 so it might not be that depending on how old these pieces are.

Answers.Text: I can clearly make out an 'x' shaped axle hole (not a '+' shaped one). Leads me to believe it is 553b.
