I am building a 1985 GSL-SE rear end for my Miata powered 1961 Sunbeam Alpine, yes I am crazy. I have a Mazda rebuild kit and boots and most of the parts are back from powder coat. The calibers are marked with L and R but the mounts are not, are they the same left and right? Also the rebuilt kit did not come with the bolt boots which I pick up at the auto parts store, but the only ones that looked the same are for a 1986 and newer is this normal? Here is a picture of the mounts. https://toyanvil.smugmug.com/Cars/Su...RIMG0003-L.jpg
