I have a Whisky CXLR carbon fork with 3-pack mounts.

I took out the plastic plugs to install bolts but the bolts will only go in half way before bottoming out (even though the bolts are several mm shorter than the plastic plugs). Of course the bolts are wider at the tip than the plastic plugs.

I thought it might be because the internal dynamo routing was in the way BUT it's the same on both sides and only one side has internal routing

So I either need shorter bolts or I'm missing something?

Any ideas? Thanks
