R107 - rear set belts or harnesses

[Rob420SL]

My SL is great with my boys in the back, at 6 and 7 they love it and just about fit. But with lap belts, if I dab the brakes and they are not concentrating, they bump their faces on the back of the front seats. Luckily so far all it has caused is a touch of extra hilarity in the back. But I dread to think what might happen in an accident.
Has anyone out there bought rear harnesses or 3 point seat belts?
Does anyone know where I can get some?
I've searched previous threads but nothing useful.

I've never heard of 3-point, but I have read about fitting a 4-point harness
on r129s on one of the forums. Maybe it was The R129 site or maybe this site.
UPDATE Try a search on this site. Search......seatbelt. There is an
article on: Toddlers......, about the safety issues you mention on a R107
