I have answers
They may not be the best but they're answers nevertheless...
So, here goes...
1. I have an 86 ttype with the ASC roof. It has the sticker in the glovebox as well as the ASC logo power switch.
2. The ASC-roofed cars basically started as a hardtop. The headliner was cut (not removed from under the plastic trim) Edges were still left under the plastic. (At least on my car they were)
3. Material was stretched and glued (not exactly sure how- but I think it was a crappy hack job to begin with). Wires were taped up to the roof.
4. Custom metal brackets were used to hold the sunroof assembly to the roof. Check your assembly for markings. Mine if from a Ford!
5. A conventional hardtop headliner will not fit due to the additional 2.5" (give or take) thickness of the sunroof unit.
6. An ABS plastic unit for a HARDTOP will not work either. (again for the same reasons as above).
7. My solution was to find a similar car with a sunroof (actually happened as a fluke- was leaving yard and saw a 4 door Buick with a sunroof and the dimensions looked pretty close.- Had to drive home 2hrs, and return the next day for my whopping $4 dollar purchase in my SUV so that I could fit the unit in without damaging it.)
8. I had the headliner covered in the correct material and when I went to put it in I discovered that the opening on my ASC roof was smaller than the hole in the headliner by a few inches all the way around. (Never ends
)
And it was a little long in the front (very minor)
9. Since the headliner had the proper size (for the most part), we trimmed it to fit in the edges and then had it re-wrapped again but this time with the hole not cut. When we did the test fit we trimmed around the hole and used the rubber trim lace to pinch the material firmly all the way around. I also think the hole for the dome light was a bit off but we fixed that too.
This is 100 times better than when it was done by ASC. It is not a perfect solution but it's what I had to come up with to get this thing covered. I think it looks pretty darned good if I do say so.
There is a possibility that the ABS unit made SPECIFICALLY for the Astroroofs could work- as you have to cut your own hole- and account has already been taken for the depth of the actual sunroof unit however, I cannot confirm this as I did not go that route.
Hope this helps a little.
