I think this may be an entry guard part # 39-032 and I want to verify this is correct before I order it.
On the base of the part is the number 40372
the long arm is marked 30470 LH
the short arm connected to the gear is marked 30841
the short arm with the clip on the end is marked 20810
on the crank housing is the number 30830
when standing outside the house looking at the window it opens to the left
