Great info! I stumbled onto drATV's website after much googling, it appears that this is actually a pretty common c70 mod: That's great, lots of previous experience to learn from! Thanks for the answers so far. I'm going to get around to bothering with the wiring conversions after I get it plated, right now I don't want some dick cop to roll up and be all "thats not plated, I'm taking it" so it's hanging out in a shed.
I'm really excited to get started on this thing, and I feel like 600 was kind of a steal. Thanks for all the input so far, I'm sure I'll have more questions at some point, too.
