Narrow rear axle
 

Hello , I need a better traction in the rear so I would like to install a narrowed rear axle for a old Mustang (about 40 inches wide) with the brakes (prefer discs)



Do you know any workshops which sell them ??
Maybe parts for dragsters ?


I need a full rear axle with 2.6-2.8 gears and with traction lock of course.


Please send some links if you have such
