Hello - is it possible to buy a retro-fit kit so I can install the PMC-Eight system myself on an existing Losmandy G11 mount that I own (it is a Digital Drive version). 
I have recently serviced the mount (regreased it, installed new worm block bearings, installing a new high precision worm and making sure everything is aligned) and now the periodic error is around +/-5", without PEC.

It is difficult to find a price for the kit only - or are they some mechanical changes made to the mount itself too (I imagine the motors would be different but they are easy to change). 

Hi Robert, thanks for your interest in the PMC-Eight G11 upgrade. We offer an upgrade kit that not only installs the PMC-Eight motor drive system but also includes some upgrades to the G11; Also in order to be able to guarantee performance the price includes doing the upgrade at our location in Arkansas. We don't offer the upgrade as a DIY kit. Here is the link to the product on our website:
