Double and single swivel seats - Can I make it work?

[matts]

Hi all just after some advice. I have a double bench with a rusty lee swivel (Not the type on rails) and am looking to make it work with a sportscraft single swivel. This is for a couple of reasons, Firstly I an fitting my leisure battery under the drivers seat at the specific sportscraft swivel allows for it. Secondly im looking at getting a twin Cabbunk and need them both to swivel in order for it to work. Has anyone achieved this or got any suggestions? I've read a post saying it was possible with the handbrake lowering kit and that both seats needed to be rotated at the same time. Im fine with this, just want to make sure before I buy the sportscraft base.
