There are many places to find the angles. I would recommend setting your main rotation axis (ie the BIG bolt that tilts the whole motor assembly) so that the inclination on the outside of that hub tube is about 56.7 degrees when at it's highest position, aiming south. You should use a declination that is about 4.7 degrees, which means that the dish should actually look 4.7 degrees lower than this, ie 52.0 degrees. However that flat plate is perpindicular to the dish aim, so you might see 90 minus that angle on your inclinometer, or 38 degrees.
However, what is important for tracking is really the DIFFERENCE in these two numbers, ie if you measure 56.7 and 52, subtract the two, and you should get your 4.7 degree declination. The absolute numbers will be adjusted accurately by peaking on a satellite, but you need to get this difference close by using the spinclination and/or the difference in the inclinometer readings.
