What Are You Doing To/With Your Car Today?

I got tired of pulling the kids go kart out of the mud, so I installed a locker in it
Got the free wheeling hub off, come to find out there had allready been a "lincoln" style locker in there, someone had drilled a hole in the hub and tapped it to run a 1/4-20 bolt through the hub, through the race, and into the hollow axle
So I just drilled and tapped it for a 5/16-18 And were ready to rock again

For my next trick, I will make some wheel spacers so I can run bigger, wider tires
