I would go one of two ways... rebuild it exactly like it is and just replace the glass, or build a header out of 2x in there if you want to use a vinyl or metal window. My concern is that if you don't have a better header to support those blocks, it'll sag a little bit and distort the frame enough to where a regular window may have issues opening or closing.
