The way I see it is , if you own a jato , then you have busted out the 2 screws on the gearbox that attaches to the shock tower , I waited 4 months for integy to produce a metal upgrades only to find out they delayed it again !!!!! So here's a little idea I had , I got a new diff. Cover and J.B. welded the tower and screws into place , hermedically of course , and it's ten times stronger than out of the box , I put some super glue directly on the screws and bottom of the tower before the j.b. weld , im telling you it's awesome strong
