Man....a little punctuation and spell checking would make your posts a lot easier to read and understand.

You can get gear sets from pretty much anywhere that sells auto parts,the best deals are probably from big wholesale outfits like Summit Racing but shop around.
Know this though,it's not just a bolt in deal,gears have to be set up by someone that knows what they are doing.
With a little luck you might find a complete rear axle with the gears you want from a junkyard or car parting out on craigslist etc. that you can bolt in your car.
That might be more cost effective but check it out well to be sure it's in good condition,you don't want to buy a piece of junk.
