I pulled my 1980's version 6 stack out and snapped some pix
I measured the bridle and got this
loweredge to clip 12.5"
clip to nose 9"
center to clip (left side is attached to the right leading/top line): 6.75"
center to lower edge 13.75"
hope this helps
This helps A LOT! Thanks! Mine is a little newer (solid plastic LE fittings, fiberglass (I think) spars, slightly different arrangement for the leader), but I think I can now see how the puzzle goes together.
