9 inch front left side drum Richardson, TX

I am proceeding with installation of right hand thread on left hub but will continue my search for a good left hand replacement. Halfafish has one but will not be available until latter this year. Will swap it out then. Regarding the whole left hand thread thing. I think it most interesting and am happy to have a car made so. I never allow others to work on my cars so even one left lug mixed among rights is not an issue. What is an issue is what I've learned regarding replacement of the studs and or drums and how destructive the process is. Is this an issue on 9 inch brakes only or are the 10 inch made the same as well?
