FYI: Sun Valleys been doing this for years. About 15 years ago (when I lived in Cali), they sold me a re-built trany for a 72 280 for $500 bucks (worked perfect; and I was just a kid). Ended up selling the car few months later to a japanese exporter for a profit.

They're pretty stand up people (great reputation). That was then, so can't speak about now but I still hear great things. If still worried (1800 bucks is still alot), credit card would be best bet.
