I'm sorry about this but I'm not sure why the MEs calculated at -60, -59, -58,...,58, 59, 60 should be related to those at -6.0, -5.9, -5.8,..., 5.8, 5.9, 6.0 in a heavily non-linear model like probit . Are you suggesting that they are equivalent or proportional or...?

Thanks again,

I believe Kit is just suggesting that you rescale the variable so it runs from -60 to 60 instead of from -6 to 6. Use the rescaled variable in the probit model.
