Well, he may have told you he went 4.10s, but maybe he forgot which one he chose because the rpm/speed you posted show that they are 4.56s, not 4.10s

That's what I was thinking, but I appreciate the help bud I'll just keep an eye on the chart and see what I come up with

This. Jack the rear end up, mark a tire and spin the driveshaft one turn and count how many times the tire spins around. If the tire go a little over 4 times around, you have 4.10, 4.5 times around you have 4.56, ect.

This method is by far the easiest and best way to check what gears are in it. None of this, "oh I turn X RPMs at X speed on X size tire in X gear" bs.

You realize that the chart is more accurate that your 'if the tire rotates a little more than 4 times' bs? Not to mention it is easier than jacking the car up, getting underneath, marking the tire and then counting and spinning..
