Thanks, Herb. Jim V. at Dynotech instructed me as follows: Install the driveshaft and with the car at ride height disconnect at the rear u joint and push the shaft as far into the trans as it will go. Mark the splined shaft at the trans at then pull it back until the u joint seats. measure the amount that it withdrew from the trans and if it is less than 3/4" the shaft is too long, if more than 1" it is too short. BTW, he confirmed that too long a driveshaft will cause a serious vibration at speed.
