Thanks Alan, if I get over your way I will be sure to say Hello!!!
I posted about that part on my Son's Volvo and questioned the need for a 2 piece driveshaft... In talking with Parts people I believe it is a Safety feature... the motor mounts are designed to give way in the event of a front end collision in order to keep the motor from being forced into the passenger compartment, so between the boy and I we deduced the 2 piece D/S is part of that equation as well.
Have a Blessed Week!
