I have a 2.47 diff out of a 380se but didn't swap the cv axles(big regret) and my stock ones are shot. Its impossible to find the 300sd cv axles new. So I bought some 2nd Gen cv axles off a junked 560. My question is will they fit or do I need to buy the half shafts for the 380se and use the other half of the used 560 cv axles
