craigslist ... rare ??

Yeh you are right the 170 was the undesirable engine for sure , but he never did give us the serial so we really do not know for sure.One thing we do know for sure is that they built 42 auto,s with a 170, and 5830 225,s .I just checked for fun the 69 Dart Swinger 340 they built 16,637 , 8834 4 spd,s and 7803 auto,s . So even with the 225 i would say it is rare enough , i also checked the total on the 69 GTS and it is very close in total also the the 225 GT,S .So the way i look at it , the guy was close enough in it being rare.
