Which constraints to use for changing a sketch radius in a sweep with out changing other points?

I have a sweep I've made using sketches on multiple planes, I need to change a radius in sketch2 that I'm using in my sweep from 2.25" to 9". I've tried constraining the sketches in various ways to keep the circled points locked, the lines vertical and horizontal, while only changing the radius and shortening the lines the radius is attached to. What would be the right combination of constraints to achieve this?

Have a look at sketch 18 over laded on sketch 2. Draw the lines and dimension the out bord ends then apply a fillet.

If the end points are 'locked' the lengths of the lines overdefine the whole. make those driven and change the diameter. the vertical constraint is yet to be added in this screenshot.
I figured out a workaround for this issue. I added new points to the sketch close to the end points of the line. Then deleted the radius and leftover lines. I re drew the lines into a 90 degree corner and used the sketch radius tool to get the radius I wanted! This allowed me to keep the locations locked and re-select them for my sweep.
