Thank y'all very much! I def. want to get it right the 1st time and at least get an all original #s matching drivetrain. To me, it's very sketchy to put in your selling description " Real Z28 w/ matching number engine", but show no proof. And what about the the rest of the drivetrain, is that not original?! Just aggravating and they could save us & themselves a ton of emails and questions.
