EGR to header nut size?

I made my own stuby wrench just for removing the EGR nut on a Crown Vic. A regular wrench was too long to fit. Took a regular size wrench and cut it in half with a hack saw.

I used an SAE wrench that was not an exact fit (just a little bit large) but close enough.

UPDATE: my stubby wrench is 1 and 1/16"

Don't remember the size but if you notch out a small section of the inner fender it allows for much better access to the nut.
