Wheel studs

[itsdiz]

I've had A-body Mopars all my life and thought I was pretty knowledgeable, but why would the wheel studs be different front to rear on my 1965 Barracuda? Someone had changed the LF wheel studs from Left hand to Right hand thread. I was going to put them back to left hand so took some off my 1970 Dart parts car but the knurl was too small. So I put the right hand studs back in and bought five more for the rear, but when I tried to put those in the knurl was too big, so I took one off the Dart and it fit, so I used those. Dart has 9" brakes vs 10" on the Barracuda which is why I thought the stud knurls were different. For reference, the front stud knurls on the Barracuda measured .555 in. diameter while the rears were .460 in.

Front drum brakes use one stud, rear drum use a different stud, front disk use another stud.

9 inch might use a different stud as well

It sounds like you may have brakes from other year cars as well

Technically, they made 8 different front studs, and two rear studs, if you count both LH and RH. All different. 4 different 9" drum type, 2 10" drum, and 2 disc brake. The rears are all 2070158-9.
