used TD-84u, aftermarket case, basically one of the new distributors the JDM importers will sell you. this one has a broken keyway which is seriously easy to switch off if you fried your distributor. as you can see the keyway which fits in the cam only has one of the two teeth it should. the engine was actually running with this as it sits but you NEED to replace the keyway, the timing will bounce if you don't. other that that there are no issues. complete with cap, rotor and everything else. basically pop your old keyway on and drive. selling cheap for $65 shipped due to the fact you have to switch the key and also the case has been elongated for shaved heads that have problems timing.
