there are rubber lines going to the rear drums. They even look similar to the rear factory lines on the GS model; but they will not work. The back of the drum(RS) has a smaller hole for the line to thread into and the stainless brake line kits(fwd)are all made for rear disc brakes. I found this out when I took my lines off and compared them. This was one of the factors that made me consider doing the rear disc conversion. Replacing just the front brake lines would not get rid of that spongy brake pedal. I did the front first and drove like that for a few days while I finished assembling the correct rear disc conversion parts.
