I talked to a driveshaft shop last fall, we took some measurements and did some research, and they came up with for $300-$350 they would take out the 2 piece driveshaft and flex discs, center bearing, make the mount for front and rear to install 2 common u joints and single piece steel driveshaft.
So would habe a single driveshaft, no flex discs and no center support bearing.
