Don't shoot the messenger people! ;) I've only had the car a month now and to be honest if it wasn't for the hassle and the importance of doing a few other things on the car I would have probably taken the rear belts out completely already; after all, a Peugeot 309 lapstrap doesn't really compliment the 60's interior does it!? ;D I'm under the impression that due to the cars age and the fact it didn't have rear belts from the factory I don't have to have them fitted, and being a (currently!) single 20-something I don't really have much call for any belts in the back anyway, unlike the PO who installed them... As I photographed I did wonder where you would even mount the shoulder anchor: on a saloon there is the rear post but in the estate there's just so much glass in that vicinity I wouldn't have the foggiest idea. The window sill might be a possibility as you say John, but I imagine it would take some modifications to be sufficiently strong enough and might still be out of the 10 degrees you mention... Not as easy at it looks obviously, perhaps the PO fixed the two ends of the rear belts, looked up at the estate glass and thought "bugger!" ;D
