So I got the information I was looking for on the PY forum. Below is a copy of that post along with a crude drawing.
" My factory original side molding is spaced back from the panel edge 1/2 inch. The front piece is 16 3/4 inch long. The front end is cut and pinched to a point. The back end is cut square. The door piece is 55 3/4 inch long. Cut at a bevel on the front end, square on the back end.
The back piece is 6 1/4 inch long, the front end is square, the back end is cut at an angle tapered toward the top."
"1) On the rear piece, is the 6-3/4" measured to the long point or short side?
2) On the door piece, is yours about 1/2" from the gap on each end, or are the fender pieces spaced 1/2" away and the door piece closer than that to the gap?
3) The bevel cut end of the door piece, does that look like the cut was made at 90 degrees and then just the rubber inset strip is beveled back? "
"Ollie - see if this crude drawing accurately reflects the dimensions and cuts you provided. Also, a couple of questions.
1) On the rear piece, is the 6-3/4" measured to the long point or short side?
2) On the door piece, is yours about 1/2" from the gap on each end, or are the fender pieces spaced 1/2" away and the door piece closer than that to the gap?
3) The bevel cut end of the door piece, does that look like the cut was made at 90 degrees and then just the rubber inset strip is bevel cut."
"Yes, the drawing is quite accurate.
(1) A more accurate measurement of the rear piece is 6 3/8 inch on top and 6 inch even on the bottom.
(2) The gap between each section is 1/2 inch back from the edge of the panel.
(3) Yes, The bevel cut end of the door piece, does look like the cut was made at 90 degrees and then just the rubber inset strip is beveled back."
