Have done a couple of the LNE FAs with ERR with electro coupler on the nose of one of them and LED lighting. Really easy and lots of room. The Alco PA sound board seemed the best for the FA. I attached the speaker to the inside of the rear door with Velcro. That and a detachable antenna make future engine repairs easier. Not related, but while you have the engine on the bench add some extra weight (old, used stick-on wheel weights) inside the fuel tank for a super pulling engine. These little monsters have no limit when it comes to pulling power.
