Where to mount 2 KRG3s on KHR-1HV

[Big]

How in the manual I have found "RCB-3J_sp1.pdf " it shows how to mount the 2 gyros on a panel that unscrews between the legs on a KHR-2HV

Problem is I have a KHR-1HV. Which does not have the axtra panel - due I am sure to the extra DOF at the hips.

So whats the easiest way of mounting them Is there a simple trick or do I have to take the tthing apart to get these in.

Any suggestions most welcome

Thanks
