Yes, that is a 4-speed L43 transmission.
The clutch kit you need for that is:

How are your clutch master and slave cylinders doing? No leaks? I know on my 1981 people in the past had spilled plenty of clutch fluid over the master cylinder and it was rusted up pretty bad. It still worked ok, but I didn't want to chance anything so I just went ahead and replaced it. We only sell original Aisin Seiki CO clutch and brake hydraulics which are an excellent replacement at a great price!
