73 Duster SS Springs 002 003 install

UPDATE: drove about 40 minutes to opening day of track. Car drove like a jalopy the way there and back. Also does not like dips, bumps etc. All excited to test and have fun (awesome weather, pleasant country drive) when the gate person noticed I was missing my fuel cap. (I got fuel in my town and forgot my cap) I reacted as a doctor informing me I have only weeks to live!!! There was also a swap meet but no Mopar stuff as usual. Parked the car and became a lowly spectator mulling over life's choices and other regrets. But wait! Upon driving home, the fuel cap was right where I left it 6 hours prior. LOL! Is this a win?
