Here's what has happened. With a suburban you have five pieces of material to install and must start at the rear. CD sent me five pieces front most and rear most pieces were die cut in approx. pattern but three middle pieces were large (72"x59") sheets. Doing a dry run with the two cut pieces I found they were not as advertised "cut for exact fit", but a bit off at best. I decided after talking with tech dept at CD to go ahead with makeing my own patterns for all of the pieces and cutting material to those shapes. Stupidly I made patterns (with gridded poster board and masking tape) for all but last installed piece (above driver/passenger at windshied). These I used to cut and install headliner, rear to front. When I got to last section I found that the suppliers piece did not fit and was short. So I have three days labor in a 4/5 installed headliner with no choise but to get same material from same supplier and hope for the best. Good news is that the tech at CD has maybe figured out the snag. Suburbans have a screw in bow above driver not floating and as mine is a '51, it may need the pickup part from the screw in style not the floater as model year would indicate.
