Will do Ed, I have to be doing a lot of bending over the next few days/weeks for the body I have under construction so I'll take a slew of pictures.
Also, you are quite right about welding a rod into the center die to indent the inside face of the curve. I didn't do that for this particular die because my purpose in fabricating the die was to do long sweeping bends as shown in the pics below rather than tight curves or 90 degree corners etc. For these long gentle curves I actually felt the crush rod might be more detrimental than helpful.
I WILL have a need for these tighter bends not too far down the road on this build so I'll be fabbing another die or two which will incorporate the steel rod concept you suggested.
