Default L-Square for measuring/setting wheel alignment

I saw in another thread where one of our members made up some plugs to fit inside the rear axle. It struck me as a brilliant idea so I made up a pair. I went on a quest and found what I think is a perfect L-Square for measuring/setting wheel alignment.
FYI - It is called: Zona 37-434 L-Square, Stainless Steel, 3-Inch x 4-Inch and can be found on Amazon.

That looks good, I did that and concluded that I would be better off checking distance to the swingarm pivot so I made plugs for the pivot shaft and use a wire rod to compare right to left.

Yup. that's what i did too. There is a drawing in the FSM showing how to make it using a piece of music wire.

Using a reference off the swingarm might be okay (maybe) but how do you know its dead on by the time you're at the front wheel? How do you do a 4 wheel alignment on a car without checking all 4 wheels?

The only way to know would be to check the alignment of both wheels the proper way then check the reference point on the arm to verify you repeat the result, then you can trust that swingarm for quick checks now and then provided the bushings never wear out. To me aligning the wheels means exactly that.

Actually they both measure 1 and 23/32 of an inch (1.719). One side you read left to right and the other right to left.
