My 69' Mach 1 had it's original trunk deck lid. They did a horrible hack job to install a 70' style spoiler. I had a repro deck but it is a 70' style with the cutouts for the spoiler brackets. I have repaired the hack job and I had to replace the back skin and frame, the repro was also 3/16" narrower than the factory. I saved most of the original and am keeping the original paint and decals, the jack instructions are quite rough as someone(why do people do thee things?
) rattle canned the trunk with black paint. Reducer removed most but the decal is bad but original. I even found the black decal wrapped around the lips on each side. It had a terrible white paint job, over blue, over some awful gold. I am glad they did a terrible job because I found original stripes and can locate them exactly where they were from the factory.
OK my question. What are the two 'X''s on the frame of the deck lid?
