I tried the California Import Parts ones, but the construction is flimsy, the pillar bracket doesn't have the alignment pin, and buckle looks like an american style.
Then I tried the Wolfsberg West one. Much better construction (I can use the original angle bracket. Unfortunetly, the return spring has little omph and leaves almost three feet of slack.
A couple years ago I bought a pair for another super I have. They are original mexican beetle replacements. They have a great return spring, and fit well. But
Or if any other suppliers sell the real mexican VW seat belts? The stock number on the box, if it helps, is #1B0-857-705A
