Need CG-5 Mount advice PLEASE

Hi again...

I started with an Orion SkyView Pro mount on my 8" reflector...very pleased
with that mount. Bought the dual drives from Orion, installed them, love
it.

Ok, I bought a 5" refractor on astroMart, then I bought a second mount which
I'm told is a CG-5. Orion told me the drives for the Skyview pro mount were
the same so I bought them. They are NOT the same. The RA drive will not
fit properly in the compartment. So, what do I need? These mounts have no
markings...I say these because I bought (damn astromart!) a nice Celestron
refractor (Jananese OTA) which came on a CG-5 mount...same story with the
drives...

Are the Sky View Pro Drives NOT interchangeable? How do I know if I really
have a CG-5? The two I bought are identical....so, the drives from
Anacortes for CG-5s should work??? Really drive frustrated....Was ready to
just order a couple mounts from Orion! They're better anyway!

Anyone know anything that can help me in this?
