what year are you taking about? A 1956 crown vic driveshaft won't be the same as a 2006 crown vic driveshaft.
The aluminum 2008 cop car driveshaft I have in my 57 Ford has 1350's on both ends. The original 57 ford had 1330.
cheers rmk57 - so its a no go have new 1310 on my 9'' and a new slip yoke foor my t5 with 1310. I think I remember corvette c4 driveshafts being 1310 each end but real short. any other aluminium driveshafts 1310 both ends?
