I may not be the queen of Ebay, but I buy a lot of junk off of there. I recently purchased a set of the Ebay VX seat belts. I learned a few things.
1. You need a torx45 or 50, I don't remember, to remove the top bolt. I got a full socket torx set all the way up to 60 for 11 bucks at Northern Tool.
2. The replacements will eliminate your ability to raise and lower the top seat belt anchor.
3. Removing the rear side panel to get to the retractor is a gigantic PITA
4. You have to make a few cuts in the plastic seat belt insert where it goes behind the panel to slip the new seatbelt into the plastic retainer, no biggie, just cut it somewhere inconspicuous. I went aft so it can't be seen from the front. I wouldn't cut the bottom, the belt will rub and could pull the insert out.
5. If you are a "free spirit" and drive without a seatbelt. If you want to get rid of the warning light, there is a small two wire harness at the base of the buckle receptacle. Disconnect it and no more light. The replacement does not have the wiring anyway, so I was prepared to short the two together to make it go away.
6. The replacement retractor housing is different than ours and only bolts in one place, but it does fit just fine.
Other than that, it took about 1 hour to do the driver's side. No problems and no more slamming the buckle in the door!!!! Hope this helps for those thinking of replacing their lazy old retractors.
