Looks like it’s 3.25” in diameter and it’s 48” u-joint to u-joint. As far as modified from stock the only thing I did was put the 7260 u-joint on it about 5000 miles ago. Unknown if the front was ever change before my possession. No vibrations what so ever before it was pulled out.What is the OD of the fatest part of the shaft and the center to center u joint length.
Lastly has it been modified in any way from stock
Looks to be 7290 on all ends. Must have been a conversion u-joint on the rear I put on.On the shaft itself are the yokes 7290?
