Greetings... did the hockey stick chainguard have adjustable front downtube bracket? ...I installed this one but it ended up crooked. There are four rivets on the guard but only two can be used for the bracket. They are proportionately spaced from each other as if you can slide the bracket to and fro... My example would probably benefit by sliding the bracket to the other two rivets... I guess drill them out and use new screws or re-rivet? Definitely not as easy as the later guards... Thanks
