Re: Removing driver's seat back rest on a 400
Those two screws aren't doing anything except keeping the backrest from pulling all the way out. And you might not have stripped them, they just spin in the bar. And there's nothing in the service manual about them either.
They're a pain in the butt. Here's what I did; remove the seat completely. It's so much easier working ont the seat this way, and you can see what you're doing. I couldn't see a thing either when looking up at the bottom of the seat, and couldn't hold a flashlight and two screwdrivers at the same time. Remove the support strut first, then there's four bolts that are a little difficult to get to at the front of the seat (easier with the strut gone though so you can open the seat more). Turn the seat upside down on a table. Now you can see the two access holes. Move the back rest back and forth a little until you can see the two screws. If they're spinning, get in the hole with a long flat scredriver and lift up on the head of the screw. It'll back off easy then. If it's really stuck, give it a squirt of WD-40 and wait a bit. It'll come off.
