Re-installing blinds after replacing original windows?

I used to have original builder windows, with some fairly high quality blinds mounted to the inside of the window sills. When I replaced the windows with some Okna 500s, I lost 1-1 1/2" depth in most of the window sills, and I no longer have space to mount the brackets that hold the top part of the blinds. I imagine this problem happens all the time - what options do I have to re-hang the blinds? I'd rather not throw them out, since they seem fairly expensive.

You could if needed drill new holes in the brackects to mount inside the 1-1.5" recessed drywall jamb pocket.
You want to catch the header, head packer, or go into the jack studs.

Not an uncommon problem at all. You can normally catch enough to still do an inside mount.

I used longer screws at an angle and it worked.
