Broken Columbia Graf. G-2 tonearm. Substitute D-2?

[AMbrowm]

Hey guys, quick super amateur question: I have a Columbia Grafonola model G-2 I've been tinkering with, and I finally got it working only yo have the tonearm break. I can't get another G-2 tonearm right now, but I might be able to get a D-2 tonearm. They look similar enough that I'm hoping I can substitute the D-2 tonearm for the G-2 tonearm, and frankenstein this guy together.
eternal gratitude to anyone who can let me know,

Woo hoo! Then all is not lost. Thanks very much Harvey, very glad to be here. I haven't figured out how to transfer my eternal gratitude over paypal yet though, so until then, I hope this emoticon will do:
