I have lucked-out on getting a bonded title in NY and in NC on my 54/55 GMC COE (in NY) and on my 1954 3106 Suburban (in NC).

I had the "door jamb" plates but they had been removed/replaced during painting.

The DMV inspectors could have refused my registration in both cases.

But, I have a lot of documentation, so they both allowed a bonded title.

In both cases they allowed the bond to be set at the original list price - they could have required a recent valuation by a professional antique vehicle appraiser (who might have valued them at 10x - 20x the the original price).
