they are pretty easy to make...i used to make and sale them for members but now i work to much...just do a search for seat brakets and plenty of write ups will come up
corbeau sells them I'm not sure how much they are. I know with the ones I got they sit a little to far forward but I intend on fixing that problem by extending the feet on the mounts and adding 2 or 3 more holes so it can be adjusted according to the size of the person that is gonna be riding in the vehicle. rather than having to have there knees pressed against the dash.
weld your stock brackets, thats what my boyfriend did for my seats and they fit perfect...

^^^some have done that with success, but they sit up way to high for my taste. use steel and build some
