8 inch posi traction conversion

I want to convert my 8 inch differential to an 8 in posi traction differential. Any recommendations on what unit to use? It will be used in a '67 Mustang, 289 V8. Not a drag strip car just street use.

Thanks for the help,
Seth
 
Thanks guys. I saw the ebay ads for the Yukon Trac Lock. I wasn't sure about that brand. I will check these ideas out.
 
You could consider using a more parts friendly 8.8 rear from a 1988-92 Ford Ranger many of those can be found in U-Pull-It's under $200 and already have the locker rear in them and use the same bolt pattern as your Mustang.Here is some info: http://www.therangerstation.com/tech_library/Explorer8_8.shtml The gear ratio is on the rear end tag if you see an "L" alongside that means it has the locker.
