KEV THE REV 2319 Posted August 18, 2019 So I was looking for a gear A for my vintage 380 Holiday Buggy . I looked at the gear B and saw it was similar but with different boss offsets . I cut a spare gear B that I had and made a spacer boss ( not essential to fit one though) and 'hey presto' I now have a working 380 HB .It also works for the 540 conversion . 1 Share this post Link to post Share on other sites
