All- Thanks for maintaining this site, it rocks- I have had sagging fabric on the pillar for years and now I will be seeking out "3m 77 adhesive" this weekend
my A-Pillars also were sagging and were stained..so i decided i would remove the existing material and wrap new material on the plastic pillars... i ended up finding a very nice pattern similar to the plastic dash pattern(tile like pattern)...the material is black and i found it at a local Fabricland store...i used general spray adhesive picked up from a local home hardwear store to make the material stick to the pillars.
only modifcation i had to was drill a hole through the pillar going into one of the existing clip holes...my clips broke when i took the pilars out of the first time. to make the job look clean i put a black plastic cap over the screw head.
cost of the job was under 15$ LOL i will post a pic tomaro...
