you can find em in junk yards sometimes, but the early ones were pieces of crap anyways, that leather junk. so go to a junk yard or find someone who has one from an 84-88 because it's rubber, and will last longer (im sure urs is warn out thats why u want a new one) and then make an aluminum rectangular baseplate for it and drill the holes where the old base mounted to the trans tunnel and then screw the boot to that custom fabbed baseplate.
