I cut the current bar down to 680. My push up measurement works out to about that. If I still feel like the bar is just to wide I will probably order a better, shorter bar. I will hopefully know an exact size to order by that time. I was able to get the grip shifter on the riser bar with the end bars. It all still fit.

I had a good ride, in the rain, on the bike yesterday evening. I think 660 or shorter might work for me too. 680 felt a little wide, especially when I used the end bars. I will ride it a while as is before I decide.

Thanks for all the suggestions and help, now I have a width range in mind to work within.
