I suggest that your mount the wood block holding the mirror on to a photographic tripod. With such an arrangement you can easily adjust height and tilt.
As for the quality of level, I have found that looking at the reflection of a plumbob string in the mirror makes a very levle surface. Adjust from two pependicular directions so that string and reflection are not kinked.
