Hey guys I was wondering if anyone was running the driveshaft Spohn. Its not aluminum so its still strong, and they say it will still be vibration free. My driveshaft is really out of balance and I am rebuilding a 28-spline 10-bolt with new bearings, 3:73's, new posi, and what not. So I figured I mine as well geta good driveshaft and do it all right. What does everyone think??
