Which throttle and choke cable for 84 JD 420

[OutbackL130]

There are two types of throttle cables listed in the jd parts catalog but they dont differentiate between them. I have an 84 model 420.

Do I need to get AM125290 or AM39536. They are listed as 3A and 3B in the parts diagram.

Also there are two choke cables listed as 9A and 9B.

Serial number dependent...
The older ones may no longer be available.

The last 6 digits is your S/N. "286927"

Order 3B & 9B

Ok thanks. Now I understand on the parts catalog where they indicate the correct part # by s/n.
