Hi Jonathan, It has been pointed out to me that I was wrong in telling you that axle length varied depending on whether SureGrip or not. Indeed, starting perhaps in '64 but definitely in effect in '65 and later years, axles are the SAME whether Sure-Grip or open rear. I had forgotten this, I am more used to 60 / 61 / 62 model-years. The part number for your 65 driveshaft is 2404228 ; same as 65 Plymouth Fury, and Dodge Polara. Same part number either side. Plenty of those in junkyards all over the place. My apologies for earlier disinformation. John
