Question PA-28-181 Engine Thrust Angle

With the plane leveled and measuring as carefully a practical it appears the thrust line is about 4 deg down and about 3 deg right...I say 'about' because I was measuring to the prop tips which of course are pitched. At any rate nothing jumps out as being an issue.

4 degrees down and 3 degrees right is what I need. Thx and have a great AirVenture.

Long story. My airplane flies slightly left wing low with the ball centered* and will turn left without constant right yoke pressure. I've checked and adjusted every control surface, cable tension, nose wheel alignment, rudder, etc. according to service manual, no joy. I even leveled the airplane and measured half a dozen points on the wings and stabilator with a laser transit to see if anything was out of alignment; no smoking gun, all measurements were quite symmetrical. *The ball is centered when the plane is leveled on the ground. The engine was inspected for prop strike and the prop replace 600 hours before I bought it; if there was any airframe damage it wasn't logged and there is no visible signs. Wondering if the engine mount was tweaked and there's more/less side thrust than normal, however, prop, spinner, and cowl all visually look to align properly.
