how stuck?
the vfc gearbox is apparently .5mm wider on the bottom and almost 1mm TALLER on the front part than the stock ics gearbox. Filing wasn't an option with that much material.
Stripped it all apart and had to do it all over in the original gearbox.

And that's why I refuse to do mechbox shell swaps for customers. One guy had me fit an APS gearbox into an ACM lower wit ha G&G crap machine upper. Hop up didn't align, receivers didn't align, gearbox pins didn't align...
