This is what I had to end up doing - fortunately I have a really old lathe that made the job reasonably easy, just take a very small amount at a time and remember the difference of timing between hand tight and torqued can be significant.
I ended up getting one of the SiCo 11/16-24 muzzel brakes and an ASR mount for the SiCo Hybrid that I have on the way.
