Completed inventory / hidden damage assesment of the wing kit. Found an exception on part AB4-187X1 1/4X12 which measures 11 3/8" x 1 1/4" x 3/16", but the part number indicates it should measure 12" in length. Sent an email to Van's asking if the 5/8" discrepancy was of concern and was tol it was not - the part is used to make brackets and there will be material left over.
