January 10, 2010 at 3:18 PM #1 The casting numbers on my toploader are<b>C5AR-7008-D W-1 K21</b>8 might be a 6 but not wearing glassesQuestions;Is K21 the build date ? If not what is?And if it is would that be Oct 21,1965mike
January 11, 2010 at 10:35 AM #3 K21 is 21st October 1965, but it's the date the casing was cast, not the build date.This topic might help :http://www.hipomustang.com/hpmx/topic.asp…e&TOPIC_ID=3450And there should be a tag on the side of the gearbox that you can go to this site to decode :http://mustangtek.com/transmission/Transmissions.html
