I also have soft-loop tie downs that I use on the bars for the front and the frame in the rear. It works great!

We all used to just strap our bikes in an open pickup bed, but the advancing years have proven using wheel chocks to be a very helpful and secure addition to just a couple of straps.
My chocks are Condors, but my feeling is that as long as your front tire can easily fit in the chock without whacking the bottom rear of the fender, it's going to work fine no matter the brand.
And bear in mind on most brands the rear flipper is adjustable, so find the position where the tire feels comfortably secure from movement. (it does not need to have zero movement, but you'd like the tire to have simultaneous contact with front/back/bottom of the chock)
As for strapping the bike in, basically we aim to "draw and quarter" the bike.
The D-rings want to be mounted on the floor, so the bike is pulled down, compressing the suspension some, as well pulling to the sides/front/back.
This is about having a bit more security in case the journey is somehow more eventful than anticipated.
We still see folks using no chock, or a chock and no straps, or a chock and just two straps, and for the most part they probably get by doing that, but at this stage of the game I'm most comfortable using the belt and suspenders approach; I just want to get the bike moved securely to another location without leaving too much room for drama.
And congrats on having the bike 45 years!
I, too, have had the one pictured to the right for 45 years (and its solo doppelganger for almost 40 years) and it has been a wonderful ride through time together, so I really understand the feeling.
