Another hint.
If you find your seatbelts going south on you (especially if you have the kind that go over the shoulder and go thru those guides just behind your head...), get some of the seatbelt webbing from your upholsterer and do it yourself. Mine are jamming real bad (they're raggedy and folding over at the guide spot causing them to jam) and I just couldn't bring myself to buy the whole assembly new (or used off ebay) just because my mechanisms were good --- just bad belts. I was looking at up to $1000 to replace them

!
Got the webbing at $1.95 a yard!!!!

--- in my choice of standard colors (I'm going silver to compliment my gray two-tone interior with black leather all-around)! Matching spool of appropriate thread for about $10. Bought about 12 yards and my upholsterer is going to stitch them for me for about $10. It's a legal thing that they have to be done in a certain "lock-stitch-something-or-other" and (I'll feel better than doing them by hand anyway

)
Now, I just have to make sure I thread them back thru all the mechanisms (winder, guide, etc.) correctly before I give them to my "stitcher-upper" guy.
Total cost will be about $50 versus $1000?
