SO GENTLEMEN
Having discounted the "MODIFY TRIUMPH and J.W.SPEAKER PARTS" option - we are in R+D mode.
I found some deep headlight rings on Ebay. They are Harley Davidson parts - Link Removed
There are non H/D parts out there (Drag Specialities) - but oddly they're more expensive and less comprehensive. There's no HD logo so why not.
imo they actually look better than the OEM retaining rings and - if you have the Link Removed fitted - they are a perfect fit.
imo they look a bit better too - so worth considering even if you don't want to do the LED conversion
Now just have to find a way to remove the 12mm required from the inner lip of the ring so that it all fits together.
Anybody got an Autopsy Bone Saw they don't need?
