I bought a 1994 Litespeed Catalyst. Great riding bike.
The issues is that the NDS drop out is not aligned with the DS. I don't know why. It doesn't look like it was a build issue, but I am not sure.
The problem is that when placing the wheel, the tire rubs on the NDS CS.
I have a tool to check the DO alignment with the main triangle and it checks out. No misalignment with the frame.
The wheel is a bit off in dish, with the need to dish it to the NDS, making the situation worse.
When I bought it, everything aligned at the stops, now it doesn't. Looking carefully at the DO I found what appears to be solder.



After removing the solder or material, it looks like the surface was never touched, based on the splatter on the surface. Build quality issue, I would guess.

What is the solution?
Given the only stress would be compression, could I just fill the space with JB Weld and file it down to be in alignment?
I am also concerned about the bond breaking with temperature extremes but at least it would be a temporary solution.
