need to covert 6v dc to 12v dc for CB radio


I want to build a 6-12v dc converter so I can use a CB or FM radio in an antique car (1930).  The car uses 6v positive ground power.

There are small commercial units available for about $100  but there's got to be a less expensive alternative.
Thanks!

That sure looks like it would work to me.
