I've got a question about a the GH F.Bulkhead that I bought for the GT2. The problem is is that the bh was made for 3mm hingepins and the GT2's are definitely not, so there is a lot of play in the front arms. I was thinking that I should maybe get some 3mm hingepins and ream out my arms with a 3mm reamer. Or are there inserts that would shim that deal up?

Thoughts or insights?

Thanks in advance!
