Tony. The real problem with these parts lists is that the sliders don't have any identifying marks related to the part number. The only thing constant is the bore of the tube. So while Drags print chapter and verse, identifying the actual part you have or want is difficult.
The mudguard mounts differ over time, flat brazed on mounts to start with, varying heights up the slider depending on model, then later two stud fixing with Y bracket to the front guard.
Lower stays can be front and back, or back only, so the lower stay lug design changes.
Brake backplates differ. Some have no anchor to the slider, using a torque arm to the mudguard mount eg half width 8." Some types use a cast in slot which engages on a tab on the leg. Yet others use more complex arrangement.
Add to that the design and requirements of the front spindle, then add at least two styles of lower clamp and you can see the possible chance of error. Finally whatever you get may have its own set of faults..dents, pulled or poor threads to name a few.
So, a bit of a minefield for sliders. Correctly identifying the yokes is another test. Some look physically identical but have different part numbers, but the same forging number. Usually down to one forging being ground or drilled and tapped to suit different model variants.
One thing for sure, it ain't gonna be easy.
Have a look at A65 sliders. Spindle and brake arrangement are the important things to go for. Ariel wheels were superseded fairly quickly, not really a good brake by experience.
