Newark series Guildsby questions

[Diggey]

Has anyone swapped out the stock Guildsby arm on a Newark Series guitar for a Chet Atkins wire handle? Does it fit without modifications to the bracket assembly or is it like the overseas made Bigsbys such as the B-70 where you have to enlarge the Bracket hole to have it fit? Anyone know? I'm thinking about doing it on a new X-175B.

Thanks in advance.
