Etank,

Make sure that you look at those witness marks on the front and rear driveshafts. They need to be aligned correctly or the car gets the shakes. The procedure is outlined in the factory service manual. There are two slashes on one driveshaft and a dot on the other. The dot must be nestled into the the two slashes on reassembly.

Good luck,
Tom
