Have you considered a chimney finder before changing screens? Patience on Ebay should get you a good one for less than $100. If you don't mind a TLR-like laterally reversed finder image and no meter it is like night and day compared to a prism finder. Not the folding waist level finder, though that is smaller and works ok with its magnifier. Compared to the pentaprism's relatively small view, the chimney finder has a HUGE, magnified, very bright, 100% view with enough built-in diopter adjustment to cover just about any eye. It makes focusing easy. It also weighs MUCH less than a prism so the camera is easier to handle. As long as I shot relatively still subjects I seldom used the prism once I bought a chimney finder.
But first make sure your focusing screen is set correctly or you'll never get better results. Best to send to a pro - I've only heard praise for Eric at Home, but a quick and dirty check is to compare the ground glass image to the image on a few strips of Scotch "Matte Finish MagicTape" or similar frosted tape to simulate a ground glass on the film plane. Tape tightly across the two film support rails, not the two outer film guide rails. Use a loupe or magnifying glass. If an object on the ground glass is sharp and it isn't at the film plane, your 67 has a problem. Check with and without the prism finder - maybe your finder is the problem.

I haven't mapped it, but I did find that my K7's center focus point is larger than the square and is shifted. It is probably centered about 1/2 the width of the square to the left. I haven't bothered checking any of the other points.
