Thanks for posting all of this up!
That's a lot of cash but there's no mystery as to where it went.
It cracks me up to think that I spent $700 on my Dart Sport back in the 1990s and it came with a perfectly fine transmission which (after some modifications) is holding up very well to a 460hp/520lb-ft small block...and I'm now seriously thinking about how I'll save up to make this happen.
