Rebuilt A 833 front oil leak

Instead of starting a new thread, I thought it would be best to stick with this one. So...I fixed the leak on the countershaft, but I also have a very small leak at the reverse detent assembly. This assembly appears to have two gaskets, one on the plug and one on the base. I have the gasket for the plug from Brewer's but they don't show one for the assembly, although Passon does show one on their site. What is the easiest way to change these gaskets without running the risk of having the ball fall out and into the transmission? Will the whole thing unscrew as an assembly so I can swap out the gasket?
