I'm not sure what you mean when you mention the window housing is too wide. Are you referring to the track that holds the balance? If so, you may want to consider our S385-28 channel balance. The attachments for this balance have wings that can stabilize it in the track. In regards to the spring weight, some window manufacturers have mixed the spring weight like you suggest, but in an ideal world you would have the same stamp on each side. I would go with the option that works best and use two of that. Finally, since you're in New Mexico, I wouldn't think you would have a rust problem. You can occasionally remove them and give them a lite spray of oil. The springs will gradually weaken as time and use goes by. The average lifespan of a balance is 5-10 years.
