Difference between e9 and e3 front sway bars.

I thought I had read somewhere on the board that they were interchangeable. I believe the rears are the same but I happen to have a set of both so I thought I would post a pic in case it helps someone.

The flatter one is from my e9. The other came from an e3.

The mounting points and the thickness are the same. But the shape is different.

I think up thru 73 they are 17mm and in 74 went up to 22mm.
