Well using the advice of others produced positive results.
Both Windlace are in.
The short piece of windlace run through the track as a trial is critical, was able to locate several pinch points. As someone else has said, I believe the factory worker after installing it must of rapped a rubber hammer on the rubber in several places along the track dimpling it enough to lock it in.
The other, being to install the rear by sliding it down first then using a wide flat blade screw driver or small pry tool to force the windlace in the track in small increments on the top and front parts of the track.
Trimming the windlace around the dash was required to get it in.
And finally soapy water in a spray bottle was needed.
Still after all that, my thumbs and finger tips are sorer than hell.
