I have also been told by Celestron that the single and dual axis stepper motor controllers for the CG5 and CG4 are interchangeable only the shapes of the motors are different.
May be able to help you out with a CG5 RA motor , I bought a couple of them not so long ago and was planning on upgrading an old Vixen Polar mount but haven't got around to it so the motors are stashed in the back of my steel locker in my garage.
I don't often log in here, so probably best if you email me , in the mean time I''ll see if I can locate that spare CG5 RA motor.
I've also got a CG4 dual axis drive box , that I don't need now (only got hold of it as backup) and I've now got two modified CG5 dual axis drive boxes (w/ autoguider port) so don't need it.

Thanks Ian,
I have the CG-4 dual drives and controller, mounted on my CG-4 head. I've only just received the CG-5 head and, having not seen any stars for quite a while now, haven't been able to try it out.
My 'wanted' ad was really because 'googling' these drives indicates that the 95322 drives (CG-4) are 1:11 gearing, and the 95323 drives (CG-5) are 1:15.
To try my motors out, I will have to engineer a couple of mounting plates to fit the CG-5 mount, shouldn't be too hard I hope, and I do have time on my hands.
I'll get out in the shed tomorrow and see what I can do, then wait for a clearing in the clouds to see whether they track.
Thanks for the advice and the offer, I'll PM you and let you know how I go.
Cheers
Chris
