Nope. Don't use those.
I've installed those in the past. Customer-supplied.
But only in vehicles that were never previously equipped. Pre-'68 HotRods & Street Machines.
They're generically designed, built to a basic minimum standard.
Which is not to say that they shouldn't be trusted.
They
will do what they are supposed to. Just being able to pass the Federal Motor Vehicle Safety Standards seat belt test is no small feet.
They are better than no belts at all. Especially when the dashes in those vehicles can be made up of more steel & chrome than the bumpers.
The belts in these trucks is of a continuous design.
Specifically designed to work within the crash test parameters of a GMT400 cabin.
If anything was ever to happen, your insurance co. may have a reason to deny any injury claims.
This what a seat belt manufacturer has to go through to pass those tests.
I don't expect anyone to read all this. A 76 page PDF. Yeesh.
It just shows what a seat belt manufacturer has to comply with before receiving the go-head to be able to stitch on that FMVSS comp. tag.
Some quick scrolling through the test procedures is pretty interesting though.
What a belt has to go through to pass is nothing short of amazing. ...and a lot of the emphasis is on the locking retractors.
The tech-ish stuff starts @ pg. 12 > pg.42, with 42 showing why replacement of seat belts has to be of the exact same OEM style & design.
With air bags & such in relatively newer vehicles, seat belt design & performance are chassis specific.
I am considering is having a set of stock belts re-webbed.
Who's good to use? I'm just learning of this method. My daughter's truck has a seatbelt that is torn. I bought a replacement from a junkyard but it's a different color.
I have more than few years experience with these guys.
Mostly for Muscle Car resto's. Perfect results everytime. Last project I used them for was a '66 GTO which was GTOAA Concurs Gold Certified in '09.
A little pricey, but you get what you pay for.
They do require a set of belts & hardware sent to be restored.
I have seen this Co.'s product.
Heard good things about them through various upholstery forums.
The go-to guys for some pretty wild non-OEM belt colors that the custom import owners like.
