Exact replacement
The wall & handset set were an exact replacement for the old rotted ones on my Western Electric 302. The only thing to note is that they don't have the small hooks clamped onto the wires to hold them onto the inside of the phone. The handset cord does have the hook at the other end to hold it onto the inside of the handset - it's the hooks for the inside of the phone that you'll need. I salvaged the ones from the rotted cords on my phone, so no problem there. You'll have to pry them off and then reclamp them onto the new ones.
