Top Ten things to do first on your "NEW" 1963 Dodge Dart Covertible

By the way valves were an easy check and set, NOS mopar electronic distributor and HEI setup coming next, new KYB shocks, found my disc brake swap parts locally (YEAH!).
Looks like new rear springs and rubber and brackets also.
Also want to get to the transmission for leaks, I find it difficult to get to when I can only get it a foot or so off the garage floor.
Still cogitating and looking for feedback on the rear end swap for bigger brakes and repercussions and how to offset changes of ratio to a 2.7(something) from the 2.9(something.)
Kah-Ching! Kah-Ching!
Thank heavens I am retired!
