Replacement of latch springs

My storm windows and screens are in good shape except for the springs which have rusted and are broken. I have good 91-009 latches which are all in good shape. I need to replace the 91-102 springs. Can this be done by just forcing them into the slot? I see that there is only 1/64th difference between the channel and the spring diameter. If I take the frame apart as you show in your video, I'll have to remove the glass and screens first. Let me know what my options are for replacing the springs. Thanks.
