Measure the inside spline length scope
I like to see from .750 to 1.0 yoke extension out of the tranny tailshaft housing from bottomed out with the car on the ground loaded ready to drive up You have way more than that on yours shruggy
The one picture of the front tranny yoke on the driveshaft, it looks like to me that the drive shaft is not centered in relation to the yoke center confused scope I'm sure it is not out of center due to if it was as bad as I see it you wouldn't be able to drive it over 20 MPH without the drive shaft breaking the output shaft and tail shaft housing on the tranny shruggy confused
