Being 1975 our Hunny already had mountpoints but the actual belts were totally shot, so I replaced the driver and passenger belts with some new Securon inertias.
They do a whole variety of configurations and can be picked up quite inexpensively on the internet - here's a quick reference of their options ;
http://www.securon.co.uk/seatbelts_layouts.htm
To my mind their more common 500/30 option has 30cm stalks which are too short for the Commer, so I've used 500/45 (45cm stalks) which works much better (although perhaps a shade too long, if only they did 500/40 !)
For our centre seat I've picked up an inertia lap belt 2220/15, the buckle option was irrelevant as none are suitable for the Commer. Instead I've picked up a spare 45cm stalk to use with this belt instead. I've not yet fitted this arrangement but it offers up OK but might require some custom mounts, however Securon make some strengthening plates which are essentially like very large rectangular washers and act to spread the load.
Ideally I'd prefer a full seatbelt in the middle but that's very unlikely although some modern cars I note have a roof mounted seatbelt loop to facilitate this ...

Has anyone noticed that Rootes vehicles usually have a grin designed into them...or is it me and the scotch in unison that thinks this?
Definately on the Commer at least ! Although with the air intake smaller than the grill the look is more of surprise [:0] than a grin

. I wonder what difference it would make if the panelwork behind the grill was painted black to look like a larger intake hole ?
