Would be nice if it was that. I just know its a beard built rear d shaft.
So....post a pic do the shaft, particularly where the shaft comes out of the tcase. Just because someone built a shaft does not mean its the right one. I see tons of fools lift a truck, tilt the pinion up and then Install a single cardan shaft and wonder why it vibes. You need a dual cardan shaft. If you don't understand the difference, read this helped me tons
