Correcto !!! People think there are 2 pins going thru the shafts. There isn't.
Once the 2 shafts are aligned at factory, plastic is injected between the 2 shafts.
What is visible is just the remnants from that injection process.
If the shafts are moved afterwards, those 2 spots shear-away from the underlining plastic
And, may or may not fall out of holes.
That's why measuring overall length is the ONLY true determination.
