No it was the hubs I think. Before assembling the wheels + hub this last attempt. I removed all the previous weights, outlined the location position and wgt in Oz using a Sharpie pen.

Post balancing + hubs the new weights and amounts and even locations were totally different on every wheel.

I got a little OCD on the new Trigo pin nuts as I had to cut the heads down .090". Although I Mic'd and weighed them all I get carried away on removing variables.

Never knew your BD was #53, sat for so long, and so few miles. Shows one that a car must be driven.
It was a balancing issue in the hub. Have not seen it done in over 35 plus years but remember the "good shops" would do a spin balance with wheel & tire on the car vs. old bubble balance. The spin balance machines like you see now were not around where tire/wheel are spun on a machine and then placed back on the car when completed. Guess if you found a place that did the early spin balancing method earlier in the trouble shooting, it would have been saved you lots of time.
Enjoy the Cobra on the highway.
Good job.

Thanks Nathan. On the On-car spin balancer I did do quite a bit of calling Mom and Pop tire shops the last couple of years. Perused Craigslist and Ebay thinking I'd find a spin balancer. I did speak with a couple 18 wheeler shops but the machines they use are way too large.

I'm not upset on the outcome or my outlay $. I don't turn wrenches for a living anymore so working on the car actually is more fulfilling than actually driving it for me. Plus it did need a lot of replacement parts and my standards are pretty high.

The car will never be "Done".
