23 or 18 spline?

@67_Slimer
You did that on the street?
With a Dart?
With like 255 street tires?
I wanna know more about your rear suspension!
And yes, your clutch is way outtawhack for street, for how you drive it. Something is gonna have to change.

But, Take a good look in your pile there for something that does not belong, like a foreign object. The only time I ever saw that, in hundreds of boxes I rebuilt in my younger years, is when a gear ate something that should not have been in the box.
dana 60 rear , 4.56s with MW axles.
Cal Tracs , 255/60 BF regular tires. the problem was I had myself and my 2 friends in the car. I'm sure the extra 500 lbs didn't help. Plus , shifting at 6500 without lifting my right foot hits pretty hard with that old school RAM paddle disc. I definitely need to change my clutch disc for something a little more forgiving.
