HELP: early a body Neutral Safety Switch and other parts!

I highly doubt you'll find a early neutral switch for less than $60. The cheapest I found one for was $78 a while back when I needed one. I assume your talking the single pin switch right? You can replace it with a 69-70 style 3 prong switch. Just find the pigtail for it and use the center pin. Don't look original but the newer switch only costs about $12 at Autozone so it's a bunch cheaper.
