Mini Spool Where To Buy?

welded the rear in my dana 35 in the grand cherokee and open in the front. beat it like i stole it and has yet to fail in many years. Well there was this one time but that was because i forgot to let off the gas when it landed back on the tires but only the axle shaft broke.
It was funny how my son was able to walk right up this hill with little effort in the grand but the cj with a tight powr-lok front and rear had issues climbing. i think it may be because i really don't care what happens to the grand but the cj is another story.

 

how it should be.
