Re: Need measurement on drive shaft..

The diff from a 350 T (shortie), & the 400t short , is 11/16 ". The 400 being the longer of the 2. Assuming that you havent moved eng position (swapped sb to BB), 11/16" should work as the shortening figure on the shaft. if you have moved stands/swapped things.....the best way is "shove a bare slipyolk into the trans till it bottoms, then pull it back 3/4 min, to 1" max. measure from the center of the front U joint caps , to the centerline of the bolt holes on the carrier bearing". this will give you the lenght of the front 1/2 of the shaft, that the D line shop can work with good luck...... L oops, figured with the weight of the truck on the wheels.....
