Here is another one for you do you have to enlarge the holes in the stock drums to use the 5/8 studs? And going to use the s/s axle package because its not somthing that will never see street use .
You will need to enlarge the holes bigger than 5/8 because of the solid sleeve over the 5/8 studs. I think 11/16 comes to mind. In the end though it is a much more rigid setup then shank style 1/2 lugs.
