I've been unable to reply back to this since the site has been down, but thanks Tom!
It turned out that my main problem with the convergence board was that when I replaced the resistors, I used a 47k in place of a 47ohm resistor, which provides the ground to the controls that weren't working (I realized this because the controls worked when in zoom mode... zoom provides a different path to ground) I DID need a couple of the magnets from Tom's neck board though. I was able to get everything dialed in pretty nicely, enough that I was content with it.
My wife helped me move the set to the other side of the room, at which point the color purity was distorted, figures lol. I've lived with that for a couple of months, until just recently, color will drop out. Sometimes it'll come back if I power off and back on again. I've cleaned and checked the adjustment pots on the 9-86 chroma subcarrier board, checked that the oscillator is working with a scope, verified voltages. Adjustments of these pots don't seem to have any bearing on color loss, neither does fine tuning the tuner. I put in an order for a replacement board on ebay; it was cheap enough that I don't mind just changing it out to see what we get.
Aside from that, I'm really just looking at finding or making the missing pedestal now
