On my 1999 XJR I’m trying to install the front crankshaft pulley damper. In order to prevent the pulley from rotating I have loaned tool 18G 1437 and 18G 1437-1 from JCNA tool loan program. However both tools assembled are 1 1/2" too short to go into the front of the pulley. The depth of the front pulley is 3" and the two tools combined are only 1 1/2".What am I missing here. Is there another adapter that I need?
