I have a 73 K5 that had 308 gears. The original posi exploded. I want to replace it with 4:10 true trac. Will this all fit in my original housing????
Thanks in advance

12 bolt axle? Yes, I'd say it would work, but you'll need a different carrier for the 4.10 ring gear. Of course if your existing one is blown up, then this should be no problem.
