Pics of lens removed
@sjefdeklerk can explain this better as he has modified his.
As you can see the 3 tabs that the screws are countersunk. There is also a ridge that the lens holder fits over.
With the shroud off you will be remove part of the lens assemble to where the shudder glass sits.
The section where the lenses screw into will need to be modified. The ridge would need to be removed and the tab counter sunk sanded/filed down to allow it to pivot.
However i am wondering if the countersink is 2mm as i recall luke bumped his out 2mm. If you can find longer screws this might work with spacers. The ridge however would still need to be removed.
The shroud you will need to shave the extra circumference to bump ipd out by.
During the mod process just after disassembly put the headset in a ziplock bag til your ready to reassemble.
