Having some issues locating the correct front wheel cylinders for 10” drum brakes on a 70 Duster.

Background:
I ordered a set of front wheel cylinders from my local auto parts store and I received a set of Raybestos (part numbers: 37171 and 37172), which are not correct. These numbers were confirmed by Raybestos this morning, but appear to be for a B or E-Body. These part numbers were called out for both 10” and 11” Drums in their system, which appears to be incorrect for an A-Body? Below is a pic of the wheel cylinder that I’m being told is correct for a 10” drum application and I also included the small brake line that attaches between the wheel cylinder and flex line for reference.

Anyone have a similar issue and/or can point me in the right direction? Below is what I had the tech at Raybestos look up and provide info.

1965 – 1967 Barracuda: Part Number 36050 and 36051
1968 – 1969 Barracuda: Part Number 37102 and 37103
1970 – 1972 Duster Part Number 37171 and 37172

The bore sizes on these Raybestos wheel cylinders bore size appear to be common at 1”, but the thread for the LH is 7/16” 20 and RH is 3/8” 24.

I'm open to other brands... thank you in advance for the help!!
