I got front and rear sets from andover restraints. They show up on google. They have the OE style aircraft buckles, and also the mounting eyes for the floor. Make sure you get the right mounting location for the fron seat ones. They do take up some foot space for back passengers. Also, make sure you dont put them too close together, as you wont be able to use a rear floor mat if they are in the wrong places.
I *think* the ones I got wwere the 75" ones for front, 60" for rear....

Also, make sure you get the backing plates for mounting. Otherwise its just a big washer to keep them from pulling through the floor if you get in a wreck...
