books4cars.com is one and there is another one, but I can't find the name of it right now. books4cars.com is probably a little cheaper anyway and they have the stuff dealer service depts use and owners manuals and everything else that's too hard to find. That's where I got these last books for my '94GT. There's more than one book here, the techmanual, vacuum & electrical, and theres a smog book.
Most likely, they only have used. mine were used. It's like about 3 - 4" worth of material covering ONLY your year. Haynes and Chiltons covers several years and is only less than 3/4 thick, so you can imagine how much you don't get with those.
The books I got for my '06 were from that other place I can't remember the name of and they were over $200 for both, but those were brand new.
For your '95, should be around $100+ for everything.
