The rule about kids is exactly the reason why I'm now trying to get seat belts installed in the back of my 69 K.

Yes, I've talked about it before...

But with the events of the last couple of weeks, it's become more of a priority (nothing major, just my wife being forced to take the 20 month old with her when it wasn't convenient for the wife or fun for the 20 month old). This is no bad thing.
I've got a price from someone to do it (in my case, it's not just a compliance plate - it also involves welding in a parcel shelf, given that 80% of it's missing), but the bloke isn't going to supply the belts. So I'm wondering what people recommend..? Do people recommend a particular brand..?
Klippan, Hemco, Wesco, any others..? What do people think of the Klippan Horizontal Parcel Shelf Retractable belts for the rear seat..? Do we still have suppliers on here..? I note that MiniSport sells them.
Are there any other suggestions..? I'd love something that looks more like my existing front belts, the standard old BMC belts, with length adjustment on the big chrome buckle, and wide red (well, it's faded now) webbing that matches the door restraints. Everything else in the interior is black. I think that most of the Klippan gear would probably look wrong next to the old belts, but, given it's rear seats likely to be used by kids, retractable would be nice...
