1963 Dart 270, is this a good price?

I have figured out the tranny, he had a mechanic put in just the newer engine ('72 Dart) not the tranny.

Uh-huh...that raises two questions

1. Did his mechanic put in the necessary 1/8" adaptor ring between the '68-up slant-6 crankshaft and the '67-down torque converter? If not, the transission's front pump bearing and seal are on the way OUT.

2. Why did he say the transmission was replaced if it wasn't?
