63 Dodge Dart, now let me see;)

Yeah, I know regarding highway speeds, I might just be on the feeder streets to get places afar. We never go very far anyway. As time goes on, I may keep my eyes open for a different axle ratio, perhaps an 8 3/4 that is if this driveshaft will work with it. I'd hate to have another driveshaft made.
But for what I do, how I drive and have 4 other classics to drive, what I have will be just fine.
I can't thank you enough for your help, way back at the beginning of my build, and of course that goes for everyone that's offer advice, necessary parts too.
