Peugeot Estate - Seating Changes?

Hi,

I've got a 405 estate (1996 model) and am looking at making a couple
of changes, partly because my family of four is about to have a new
addition.

First change is I'm wanting to do away with the middle lap seat-belt
at the back, and put in a standard shoulder-fitting one. I don't even
know if this is a possibility, it's just I'm not sure how safe the
lap-belts are.

Secondly, I'm looking at putting in some additional (rear-facing)
seats at the back (ie. in the boot space) for the children.

Does anyone have any experience of doing something similar, and know
where to go to have it done, and approximately how much the changes
might cost? I'm a little averse to going to the local Peugeot dealer,
as I'm sure their charges would be high, even if they did take on such
modifications.

Thanks in advance,

Steve

PS. FYI, I'm located in central Scotland, should that be of any help
with my questions.

 

They are fine, a 3 point belt will slightly decrease injuries.

umm.. so one kid gets an upgraded seat belt, while others have to
chance it in the rear crumple zone?
