This page has a few interesting things. First up is a Hayden oil cooler, a straight off the shelf item you could buy anywhere. The Streamliner gas tank and wedge oil tank never made it past prototype and in to production near as anyone can tell. The AEE Sportster oil tank we sold some of but not many, great fit on our frame though. One of the genius things AEE did (Dave Brackett thought it up) was using a square center post. WAY easy to mount to square tube instead of round.
