Converting Futaba Servo Lead Connectors to JR/Spectum

[ICM]

I just picked up a Blackhorse 61" Spacewalker from a local seller. However, he flew Futaba and I use Spektrum. The Futaba servo lead connectors don't fit in my Spektrum AR 620 rx. I'm about to dremel off the small rail on on the side of the plastic connector case so they fit. Any hints (other than don't cut your finger) before I start?
