11001 Differential Pinion Depth Checker Kit Gauge Tool Compatible with Ford 7.5" 8" 8.8" 9", GM 10-14 Bolts, Compatible with Chrysler, Dana 30-80 and Most Differentials

Edit 2: company did refund me for the issues. I relayed the problem and a possible solution and they are working on fixing it. The set screws moved during shipping which gave in accurate readings for calibration. Once they get those set screws to not move, the setup should work well. Every thing was machined well otherwise. Give it a try, I have high hopes they will address the problem. Cheers.Edit: Company reached out and is fixing the problem. We will see if it gets fully resolved.I keep getting my readings at almost .070 off of what they should be for my 12bolt Chevy.

To start, the hole for the dial indicator is too small the the supplied dial indicator would only fit with substantial force.The calibration tubes do not hold calibration. The calibration tubes have an Allen cap screw in the end to set the calibration. However, the screw in all three tubes is loose and there is no way to tell how to set the tubes to the proper internal length or for them to hold the setting.The pucks do not fit their specified differentials. In my case I was attempting to place them in a Dana 60. The puck was machined oversized and would not go into the housing without damaging the puck.Lastly, the whole kit wreaks of pollution. The smell got in my clothes and it stunk up my garage. I’m not sure what kind of Toxic Avenger sludge this thing was coated in but it was awful smelling.
