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

I replaced the idler arm already with a Moog from Amazon, I am looking for a quality manual steering box as the car does what we called down South "Bugger Hunts!". I also have a Moog Pitman Arm to replace. And will be going through the front end replacing bushings and ball joints and tie rod ends.

Can anyone vouch for a box from CarSteering wholesale or suggest a reputable rebuilder?

Also it occurred to me, how do I check the rear springs?

Thanks!
