I am in the process of converting to 911 ebrakes. I have done a search and there is lot's of good info and pics. I have done the grinding to get the ebrake hardware to fit the 914 hub. I have it all mounted. I have fabbed and welded the stationary piece that the ebrakes have to stop against. However what I can't figure out from the pics is what are the rough dimensions of the transition/bell crank piece? I have moved the OEM cable mounts so I know where the cable will end and I have left room for the swing arm to do its thing but my head is stuck on this bellcrank. Can anyone give me the dimensions of the pieces they fabbed? And what did you use for raw stock? I am brain dead on figuring this out (IMG:style_emoticons/default/dry.gif)

If you don't like the bell crank approach, you might be interested in the way I did it. I cut down two 911 parking brake cables, made special end fittings for them, and attached the outer ends to the stock 914 cables externally with the same clevis and pin that used to grab the caliper lever. You wind up with stock 914 cables, and stock 911 parking brakes (both bow-ties functional). The only special parts are the cut-down 911 cables, the end fittings for them, and the extra weld bracket to hold the outer end of the cut-down cables - five parts total per side, counting the cables. I've had it working on my car for a year and a half now, and it seems to work really well.
