You posted so much information I'm re-reading your posts and answering questions as I find them.
Regarding tires: STAY AWAY FROM COKER. If the car is a trailer queen going to judged shows, then Coker is fine. If it is a car that will be driven, as yours will be, then avoid Coker at all cost. Their repop tires are absolute crap and cannot be balanced. They're built on worn out molds and the imperfections are rampant.
I had Coker Classics on my Cadillac and they were the absolute worst tires I have ever had on any vehicle. They were wobbly, noisy, horrible handling and to make it worse, one of them had a belt separate with less than 10,000 miles on it.
It isn't just me complaining. Search car forums and talk to people at shows. Coker tires are universally despised by people who actually drive their cars.
What tires do I have on my Cadillac now? Diamondback radials. Diamondback will be able to manufacture those triple red line tires in your photo. They take virtually any modern radial tire you want and "erase" the sidewall and vulcanize new whitewalls or redline sidewalls onto the tire.
The tires in the photos below are Yokohama 700R radials that look like bias plies from the 50s. They are the absolute best tires I have ever had on this car.
If the tires you want are not in DB's catalog, call them and they will make whatever you want.
They're expensive but you will not be disappointed.
