Has anyone tried replacing the early pocket castings of a GC 1-3, with GC4 castings? I know the design is quite a bit different and it would take some work, but I'm curious if anyone has done it, or if it's even possible.
I have not worked on a GC 4, so I don't know if the rails are longer, allowing them to fit under the edges of the castings (as opposed to the flush fit of the GC 1-3).
