Seat Track question

[1969 Project]

I just replaced my seat track as the old one was broken and missing pretty much everything. My question is does anyone know how far back the seat should go? If I remember correctly before I replaced the seat track I feel like i was able to move the seat back a little more and I am not sure if that was due to it being broken or if i am not doing something right with the new one. I am not a tall guy and I feel like my face is smashed against the windshield. The back window to the back of the seat is about 4 1/2 inches. I attached some pics (sorry not the best) Pic 1 is obvious, Pic 2 is top view and Pic 3 is side view to gas tank.
