Made some changes

Hello all! 

I made some changes to the site. I tried to set it up so it's not so overwhelming, and easier to navigate, so you can find what you need. I also have it set up so you can type the part number for a part you are looking for in the search box, and it will link you direct to the part if we have it or use that number. If anything seems confusing, or you can't find it, please let me know. 

Thanks all!
