Need Replacement for R30842 with short arm probably 4 7/16, but long arm is about 5 1/4 (not 10 3/4) 39-032

Thinking I need a modified 39-032

My long arm is about 5 1/4 not 10 3/4 as in the 39-032 version

...so I need a 39-032 with a 5 1/4" long arm (not 10 3/4 as in the 30-032)

My window hinges are on the left side of the lever

Does that mean I need the 39-032 type of lever?

...or do I need the 39-031 version

Also I need 4 covers and 4 handles

similar to 39-032 I think (is that for left hinged windows or do I need the 39-031 version)

Also need the appropriate screws
