Its really easy. 

Just make sure you leave the Yoke, and all that stuff alone. Just transfer the logic board only. The CRT/Yoke assembly is probably the same. 

If you take off or move the yoke on a color CRT, you are in for a rude awakening. The alignment process is convoluted and a nightmare. 

As far as the anode lead is concerned, Just ground a flatblade screwdriver through a 100K ohm resistor, and slip it under there. 

the CRT Neck driver board is probably siliconed in place, with a razor and a VERY CAREFUL process, you can cut it free and unplug it. Its far easier swapping the whole assembly with the CRT neck board as well, than replacing the lower board leaving the CRT board intact because that involves alot of soldering.
