I've searched the archives on master cylinders and have not really found an answer to my questions. When I switch to a dual cylinder, will I have to access it from under the truck to top it off or when I am bleeding the brakes or is itm still accessed through the floor? Also in one of the old threads, I read where one company told a guy that the dual and bracket would interfear with the clutch and could only be used on the automatics. This sounds crazy. Any thoughts? One more question. I have looked at alot of suppliers , and the brackets and related parts all seem the same, most suppliers evn use the same illistration. Is there any difference in the mounting brackets from one supplier to another? Thanks for all of your help.
