That's more than a little ridiculous. Understood on the accessories though, I couldn't really tell from the pic, but I guess considering it came out of an 80s vehicle, I shouldn't be too surprised how convoluted the bracketry was then.
Happy about your find though-at least it's all looking good so far and you plan to go through it. I recall you mentioned something about kick down cables...if you need one, I'd recommend the lokar setup...worked well in my car; easy to configure and installs cleanly.
