Default Rally II balance

I’ve read a few threads about this but thought I’d start my own to see if I can find a solution.

Car is a 77 Trans Am I bought with Rally IIs on it 15 years ago. Drove it very little back then and since changed to 15x8 snowflakes for the last 12 years or so. Tires needed replaced so I decided I wanted the Rally’s back on. In the meantime I discovered that’s what came on the car new and I like the look so I want them.

Anyway, new tires installed and balanced and I had bad vibration. Returned for another balance (this time weights on the outside vs the inside like last time) and it’s better but not great. I then read some threads here about the proper way to balance lug centric rims which the shop hadn’t done before but after calling them, found out they have the ability. So back we go today (7th trip there mind you) for the new process and they’re still unbalanced. Slightly better than they were but not great. I was told one rim was bent slightly but the others appeared ok. I’m hesitant to just return to the shop without a different game plan. Any ideas? It feels like 2 of them might be “good ‘nuff” but I’m running out of ideas on the others.
