Cool beans! I always ran the stock inner seals too.The clay option worked out well. I used some detailing clay and formed a 3/16" thick disc the same diameter of the axle and placed it in the left side of the differential. I then installed it back into the housing. I removed the rubber O-rings from the green bearings (didn't want to damage them) and installed and snugged down the right axle first (opposite of the clay disc). I then installed the left axle, snugged it down, and removed the left axle...clay disc was untouched. I removed the right axle and differential... now in the process of getting it all back together. Thanks for the help...
