Spirovent

Has anyone changed just the top of a Spirovent? I have one on a system that is not working/weeping/corroded. I'm going to flush the system of old antifreeze (previous service company never checked it) and refill as needed. I can't change the complete Spirovent as it's piped in steel into the circulator manifold (8 zones). Thought about splitting a new unit and swapping the top. Thanks
