Heel Contour Size how tall for the DIYer?

[grimwolf]

So I purchased a nice swamp ash strat body from the in-stock section due to its weight and grain. I did not have the option to add a heel contour and was planning on doing it myself.

Can someone please give me the dimensions of the red areas. I need the left and right topmost edge measurements.....as they are slightly different.

Thanks for any help.

Looks like 5/8" and 7/8" here. Tough to be exact with the rounded edges and everything assembled.
