Has anyone been able to install an Allparts neck in a highway 1 (mine is the newer model with the RW middle)?

I measured the width of my neck and its 2-1/8" and the allparts neck im looking at is 2-3/16"...seems like i would need to widen the pocket some correct unless someone has installed one before with little issue...

This is the neck i was looking at...any info would be cool. Thanks

wanted to bump this up...anyone have troubles installing a 2-1/8" width neck in a 2-3/16" pocket? I know its only 1/16" but would i need to modify it to make it fit?
