Those frames were made by ALAN probably 20 years ago, so i really doubt ALAN is fixing those frames anymore because they were discontinued zillions of years ago, always u can send an email and ask if they still have lugs moving around OR find another frame from where to get a good lug and replace it, this thing it is glued so it is not a problem to put it back together, but pretty much u have a dead frame now.

Just a crazy idea ok? Have u ever tried to use kevlar/ fiberglass and carbon fiber to fix it? U need to reinforce the whole area 1st with fiberglass then use CF, it would look weird but the frame would be usable.

Good luck
