For those of you in the sunnier states who can't locate T-top shades at a reasonable price, I may have an answer. I went to a hobby shop and bought two sheets of paper-covered foam about 3/16" thick. I also got some brown wrapping paper. Laying the T-top upside down on my work bench, I used the wrapping paper to make a template of the glass portion, including the hole spacing for the screws, transferred it to the paper-covered foam. I cut it out using a razor knife, including the holes for the screws. Inserted under the edge of the trim on the lock side, without the hold down screws it has stayed in place on my '88 300ZXT for a year in Florida, and another year and a half in Oklahoma . It could be dressed up with a vinyl cover. The total cost was $4.00 for the two sheets of foam, and a buck for the wrapping paper.I have since done it on my '82 280 ZXT 2 + 2.
