Ok, point made, terminology has moved on since my days. I bought my 1971 model LandCruiser in April 1972 as a one year old used "Cruiser" with 7,600 miles on it. It was my daily driver for about eight years, then over the following six years it got decreasing usage. The brakes were a constant problem pulling to one side or the other and because of a near accident caused by the brakes I stopped driving the car altogether in 1986. It's been parked in the garage ever since but I promissed myself never to sell it and that once I retired I'd get it running again. So here I am, retired and trying to keep this promise to myself. I'd like to do the work myself, but I'll probably give up and pay someone to do the really big stuff like the brakes, clutch and other miscellaneous items.
Not trying to be a tool...

It looks like Toyota Marketing struggled with the same product identity issue back in the day.
I think it is awesome that you still have the one you bought new! That is cool.
Don't feel bad about the idea of hiring a qualified professional for something as important as your brakes, just make sure you use a knowledgeable pro. A friend of mine, who is a very skilled wrench, told me that if it is not something I enjoy doing, and not something I am good at, why not hire the job out? Made me feel better about paying someone to do something on my Cruiser.
Drum brakes require constant adjustment, otherwise they can pull (as you found out). A modification you might consider is adding disc brake outers to your axle, or purchasing a front axle already set up with disc (and maybe has knuckle service done already!).
Good luck!
