5.0L Duraspark distributor, box and wiring - used

https://www.ebay.com/itm/265251857483?hash=item3dc23e244b:g:QQAAAOSwYuBhCTuU

That is a buy!  A dizzy, two DS-II boxes, and the DS-II harness for $65 inc shipping!?!?

WAIT!!!  The grommet color is green.  What I've been able to find says that is a DS-I module, not a DS-II.  Apparently the changeover happened around '75 and there are some wiring differences.  So I'm not sure that wiring harness will fit a Bullnose truck.  

To get started if someone is interested go to:
