Rear Indicator Stem length R1100gs

[kondorpilot]

Restoring my 1100 to original spec. Can anyone confirm what length stem was factory fitted to the rear indicators on a 1999 model?
Apparently there are options of 28 or 50 mm

I'm pretty sure mine are standard. It's a 1999 model 1100GS. Rears are 75mm, fronts are 50mm.
