In order to use the dsm halfshaft on the Driverside you will need to cut 3/16ths of an inch off of the splines on the intermediate shaft. (splines that go in to the transmission.) You'll want to just get a colt gt half shaft for the other end of the intermediate shaft. For the passenger side just get a colt gt axle and call it a day.
Oh and you'll also need to silicone two axle seals together on the driver side for the intermediate shaft or it will leak like crazy.
The copper looking seal on the left is a factory awd seal and the black one on the right is a factory fwd Dsm seal. This is the orientation that they will need to be silicones
Together.
This is what they will look like all said and done. I sealed them together while on the shaft so I knew they were perfectly straight.
