I need to replace a tension spring that looks a lot like your 70-011, but the length I need is only 2-1/2". I don't have a lot of extra space, so 3" would be too long. Do you have one this size or know where I might be able to find one?

How about our 70-030 corner spring? This doesn't need holes to install. You would just slide in at the corner of the screen.
