Hi,
Look at picture #5. The upper side of the swing arm is similar to the bottom side. There you can push the stainless steel plate in the opening (5 mm x 15 mm).
On the bottom side I have drilled a 10 mm deep hole with a ISO M5 thread to attach the plate with a ISO M5 screw. The hole in the steel plate is 10 mm from the outer edge and has a diameter from 6 mm for the M5 screw. You have to be careful with drilling the hole into the swing arm. Don't drill in the wrong angle!
Instead of the long nut you can use a threaded round steel and welding it in the middle of the steel plate. The steel plate has the dimensions 40 mm x 15 mm x 5 mm (please translate all dimensions in inches).
You have to break the edges and corners of the plate (hope this is the right terminology), because the opening in the swing arm is not a real square.
OMG...my english is horrendous
I look for more pictures.
Cheers Buk

Well it is one way to do it.
The way I do it is just drill a hole and pop in a rivnut : Rivet nut - Wikipedia, the free encyclopedia in the box section of the swingarm......
No fuss and easy
