I am looking for information regarding the outer diameter of the factory anti-roll bar and the wall thickness for front and rear, automatic transmission cars w/o sport suspension and with sport suspension along with the paint color markings on the bars. Supposedly all of the bars are hollow. It is my understanding that the front bar for the sport suspension is larger in diameter than the ones without sport suspension.

On the rear, it looks to a bit more involved. There seem to be four different bars. There are two early bars (w/ and w/o sport) which have a "v-bend" between the bar mounts and two later bars (also w/ and w/o sport) that do not. I have been told that all four are the same outer diameter with different wall thicknesses.

Could I persuade some people with stock bars to grab some calipers and pull some measurements off along with reporting the paint marking color for the respective bars?
