6V to 12V converter

I run a 6V positive ground system. I have a Laycock overdrive. It uses a solenoid to engage the unit. I want to install a 6V to 12V converter for the overdrive. I have not found a positive ground converter.
Is there a way to use a negative ground converter on a positive ground system? Or, is a positive ground converter available?
Your help will be greatly appreciated.
 
OP asked about 6V+ to 12V- converters. I installed this one I got from Bert's. Set up a 12V fuse block with fuses for the 12+ (load) and jumps for a common ground 12-. You need to be careful that you do not connect 12- ground to the chassis, just to the converter.

But it acts a bit funny. It powers my CB through a cigarette lighter adapter just fine, but for some reason won't charge my phone through a cigarette lighter USB adapter in the same socket even though that adapter works fine in my other cars. I'm going to have to experiment to see just what will charge through the system, I have a rechargable jump box that has USB output that I may be able to McGuyver to work to charge my phone.

Thanks to all who responded. I have been running the Laycock for over 10 years. Recently, it started to flutter in and out of overdrive when engaged. I thought perhaps the 12v would keep it engaged.
The Model A Gods took pity on me. I was under the car yesterday and found a slightly loose connection at the overdrive. Tightened it up and the overdrive again works perfectly. Sometimes the smallest unnoticed issue can be the answer.
 
The solenoid is just an electro magnet. It doesn't care about polarity. There are some that are not polarity sensitive but not as common.
