This is my 2nd of 3 inquiries - all for different windows, I did not want to confuse with all photos and descriptions in a single request.
I'm pretty sure I have the right part selected for our Viking single hung windows:

S395-33 (3230 model for 20lb windows)
Marking on spring load balancers is 3230 JK
Figured since I had question on our Milgard (just submitted) I'd verify I have the correct part selected for the Viking windows.
