Can cracked Section Sleeve of Lamy 2000 fountain pens still be repaired?

[Dr Jim]

An original (Makrolon version) Lamy 2000 fountain pens purchased some time ago from a reputable USA dealer has a crack in the Section Sleeve resulting in a ink leak. This happened quite a while ago since I did not know there was a possibility of repairing it. Recently I discovered in reading details provided in the German Lamy website that this is a relatively common problem with earlier versions of the pen and that the pen could be repaired if returned to a registered German dealer. Is something like that possible in the USA? My understanding is that the repair involves replacing all of front Section with a more robust stainless steel/Marolon combination.
