Congrats with finalising the project! Car looks awesome again!
Only point of advice I could give is to get rid of the Fram-filter in favor for a Wix (NAPA) filter.

I also see your car has the rubber-mounted crossmember at the rear of the torsionbars. My own '65 300 convert doesn't have this, but a 2-dr HT I have parted redently did have this crossmember.
I would think it is to improve ride-comfort.
