I registered my 72 K10 in California (from Washington state) and my 75 Jeep CJ5 (Nevada) with no issues and no emission equipment inspection on either. The DMV I dealt with wouldn't know the difference between a rosette rivet and regular one. (That was also my experience in Oregon where I had to show the kid where the VIN plate was.) Coming from Canada is probably what tripped the DMV to look harder or you just had the bad luck of going to a DMV location where the register was not comfortable with a Canadian import.
