Welcome to the thread of madness and wisdom. Guaranteed to get a bit of both.
I’m not surprised one side is different from the other, it is common on these cars and often a result of poor factory quality control plus poor restoration.
The front suspension settles over time and each side can settle differently. I had my new torsion bars set in my ‘69 GTS to exactly the same height, but after driving it a few hundred miles, the two sides settled differently and I had to re-adjust the t-bars all over again.
Even now after a few hundred more miles, it is off a little on each side and I will need to do it again.
