i took out my headliner today. can i get the sponge backed headliner at a fabric store? i had the name of the glue but i cant find it. its made by 3m. any help?
No idea, but any auto upholstery shop should be able to sell the fabric to you.
As for the glue to use? Different people use different things. I've heard of everything from generic spray trim adhesive, to contact cement, to polyurethane-based glues, to... etc. The only negative comment I've ever heard was that some spray trim adhesives let go with age. YMMV.
im going to mount them on the small triangle of plastic in the corner of the glass above stock mirror. how can i get that out? i took the one screw out but is sticking near the dew strip. is it glued up there?
I honestly can't remember what holds the leading edge of those pieces in. I have a few of them in a bin at home though--if I can manage to wade through to where the bins are stashed and find the right one, I'll take a look and let you know if I see anything helpful.
can i find replacement speakers for the ones behind the seats? weird size.
4" x 6" I think. Don't quote me on that. Measure them, do a few searches online and/or talk to car audio retaillers. If you can't hunt down an exact replacement, pick something which sounds nice but is physically a bit smaller, and build yourself an adapter plate. It's not as painful as it sounds.
