I believe Whiteline currently supply a rear bar which mounts on top of the front of the leaf spring as well as under the axle. I’m not a fan of these mainly due to the tacked on appearance.
Early bits sell an EH bar which is a bit expensive for my taste. Gledge has one of these fitted to his hard charging FB sedan.
Greg EK 283 has fitted an XK - XP falcon 18mm bar and for half the price I had decided to get one of these to go on one of my cars. I plan to fabricate proper mounts so the attaching hardware mainly won’t be used, apart from the insulators, saddles, washers and pins. The falcon bar has the deviation around the diff centre housing slightly offset but not noticeable on the car.
Then today I bought a NOS Selby 18mm EH bar on gumtree. Selby shut down their business some time fairly recently I believe.
First photo below shows the whiteline bar over the Selby

Second picture shows that the Selby bar is slightly wider between the outer pivots but I don’t believe this is significant

It will be some time before I get around to fitting one of these. When I do I will post the results.
