We always use the serial # taken directly off the interior data plate form where its marked, serial #. Logical to me. Lender is coming back with the affidavit of affixture wanting the VINS to be the serial #. The input box does request serial#/VINs. The VINS differ from the data plate info. Im making a comment in the serial# section and adding the aff. of affixture as a pdf to let them decide what they want. What is the difference?
