Edit Movelist: Adjusting Ledge Grab Box

[cramazzratazz]

So I have a custom moveset I've been tweeking and, as one very inexperienced with rel file edits, am having one final difficulty before the moves are good and balanced. The recovery move implemented has an incredibly short range for landing that ledge grab (substantially worse off compared to literally every other character in-game). Any advice on where and how I can adjust the ledge grab range on this specific move?
