Well, bad news, good news... the more I checked out that kangaroo cab, the more I realized it was not going to work. Every single edge has water damage and is swollen- I didn't really hit it in the video as I actually thought the t-molding was too small! Plus, the whole upper light/marquee area has mouse damage (really bad), and about 1/2 the wood was needing replaced over the whole cabinet. Thankfully I had no money in it, and there are still enough parts there to justify the gas it took to pick it up. It will be used, just not for this project.
So, the good news... at auction this weekend, I bought a nice Raiden II in a converted... Kangaroo cabinet! But this one is in excellent shape, the CP is almost setup how I need it (need to drill 1 more hole for DX, per player), and the PCB, without exaggeration, is pristine.
So, the project remains the same, I just saved myself a lot of time and effort (money-wise, it was a wash... after adding up costs of parts, new wood, glass x 2, bondo, wood hardener, etc., it was about the same to just get another cab). And now I have a Raiden II pcb (have to consider if a Jamma switcher is in order here) and a spare 19" monitor (with signifigant Raiden II burn in, but still nice to have a backup).
Anyway, just an update. Will probably not be making much headway on this for about a month, but felt like sharing my auction victory.
