i know you guessed it in your first post but i was just letting others take a guess at it before i said what it was
here are more pics
I just checked every picture on my PK/JD DVD and this is what I found. In the picture on the left, the U brackets to the right are those off of a 1967/1968 Jim Dandy but to the left, the "head' isn't the same or is missing something. The picture to the right doesn't look like either of the blade styles or years listed in the DVD. Are there any more parts that you can get pictures of? Or, if you PM me your email address, I can send you what I have so you can see what I'm talking about.
