69 signet distributer conversion

IIRC they are but you can get a longer rotor for some reason....60 to 87 is same cap part number!
Gets stranger as the 74 rotor is cut deeper on the inside. It rides high also bc the rotor key is wider and it will not drop all the way in. Bought the whole kit to avoid issues like this. I have a rotor issue now. Prolly end up dropping the 74 Dist. in.
