Measuring the bolt spacing will have to wait til I get home tonight, but just staring at a ruler, this distance sounds small, as if these were the early calipers. All late calipers have 2 bleed valves, top and bottom, on each caliper, while original early calipers have only 1 at the top of each caliper (late replacements for the early calipers have 2 bleed valves.) BTW, there are 2 different type 4 calipers. The early type 4 caliper is the same as the late type 3 caliper. I don't know the ATe numbers. Repair kits should be available there; I can certainly get them here, but rebuilding is difficult for the beginner. OTOH, this is a useful and valuable skill to cultivate. In my opinion, the original style type 3 calipers are much superior to the later replacements, so if you actually have originals they are worth saving. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
