I've leveled points 1 and 2 (right and left rear) and am trying to do the front point 3. Problem is that the manual says "adjustment point 3 has a stamped "3" on side of front hanger bracket." The bracket on my deck does not have this "3" stamped on it and the bracket looks completley different than the one in the book.

Where do I take the measurement from to complete this process?
