My headliner had started sagging and while looking for ways to fix it I saw some photos showing that you can just take it off and run without a headliner. I tried it and it seems to work quite well. Photos and description below.

The sagging is caused by the foam between the cloth and the backing deteriorating. There is really no simple solution to fix it. It needs to be removed. Once the hardtop is off the car (Torx T40) you need a security torx T30 to remove the brackets on the rear which attach to the mounting bolt. A cheap bit kit from Harbor Freight has the security torx. If you are only pulling the headliner there is no need to take off the two side trim pieces (no need to drill out the rivets); just use some needle nose to pull it from the gap.




In case you're wondering, the headliner weighs ~170 grams.


I used brake parts cleaner and shop towel: soaked the shop towels in brake parts cleaner and let them sit on the adhesive for ~10minutes. I used towels and microfiber to remove the adhesive.

Midway through I started using a plastic brush which attaches to a power drill. This worked quite well and saved quite some time. First half took ~1.5 hours, second half ~45 min. Total time with removal and installation was ~4 hours. I quite like the look of the body colored roof and it also makes the hump a lot more visible which I think is a cool feature of the hardtop. I am not sure if the quality of the paint on the inside is always this good.



If you're curios my hardtop without the headliner and hardware weighs 8.75kg and the hardware was 462g.



Final result:

Some hard tops have a beautiful finish underneath the adhesive, and some are so-so. Mine is pretty decent, save for a splash of orange in the middle :shrug:

Nice job! In the end, it's good 'ol mechanical action that works best to remove the glue. My paint was not great, but not so bad I couldn't live with it. Makes the car a bit louder though.

Wow! No wonder you decided to run with no liner. Looks terrific! Handed mine to a place for relining and never saw what was underneath and now I'm curious! Either way, nice work!

Most of the noise in my car is from the hardtop weatherstrip squeaking. Silicone grease does not seem to help.

My BRP hardtop has just started the dropsy. I'm going to remove the material and hope I have a good paint job. Since the BRP shows at the space between the top and the backlight, I expect the result to have a we-meant-do-do-that look.

Reminds me of the new Chev pickup I bought in 1975. No fabric headliner, just a double-skin steel roof painted the same as the exterior forest green. Even had the same sort of lowered strip in the center, even though the exterior of the top had no such feature. The double metal continued to about 6 inches below the backlight. This allowed me to do two projects cleanly: Drill a hole in the roof for a CB antenna and route the coax between the layers of metal. Make an attachment for the top strap of a safety seat for my little daughter.

I had the sagging headliner as well. Took it to an independent local interior guy to replace and he put in a thin layer of dynamat noise insulation on either side of the center rib to reduce noise a bit without reducing the head clearance. Then he put in a nice black ultrasuede which looks awesome. A little pricier than most quotes I saw on the forum but I'm happy with the end results.

Currently working on this myself. I soaked it with goo gone and it seemed to help a little bit. I used a plastic razor scraper to get the foam cleared. The glue beneath just takes some muscle. Taking my time and will switch to a plastic brush with a drill to hopefully save me some tedious manual effort.

That should work, I used 3M adhesive remover. Smelled like vinegar which went away after a day or two. Did a great job removing the adhesive and sprayed mine with black coat.
