Thanks for responding Dan.
The flange that matches to the kick panel is 1/2" too far back. In other words it would seem the dash needs to be father forward or the radius section where the dash joins needs to be trimmed.
If this were corrected by timming, the upper flanges that fit under the window trim would not line up correctly though. Also there are no holes or countersink for the shoulder screws in the mid section of the trim.
While on the subject, is there a difference between saddle tan and tan in the 70 Challenger interior? The paint I purchased (saddle) is a little darker that the original trim piece.
