You have some mad skills Sir! That looks fantastic to me. Very well done!
For finish options, look into Cerakote, used a lot in the firearms industry, super durable and very easy to apply. There are definitely colors (several shades of black if I remember correct) that will match to the Ranger interior.
And, if we are voting on a gear shift lever, my vote is for the pistol grip design from an early 70s Mopar, that would fit sweet on the Ranger's shift rod.
I am also interested in anything you have made for your AG stuff! Are you on a AG related forum with info? please share.
Road runner style!
