I need the truth about wheel adaptors

My two cents worth here............YEARS ago, I felt the same way, bought adapters, tightened correctly-even used red Loctite........drove Dart for approx 100 miles-no probs.

Two days later, I was on a trip to my Mom's and back(40 miles roundtrip) and coming home, lost the left rear wheel at 65 mph........it was a sobering ride to say the least!
Damaged the wheel beyond repair...........AND the left quarter panel.

LONG STORY SHORT- If I had changed over to the large bolt pattern, I'd actually have been about 50 bucks ahead total...........not to mention still having the original quarter panel......and the original paint............and that pair of drawers.......they were REALLY super comfy................
