inertia passenger seat belt help!!

I've just got a passenger inertia belt for my 1974 series III & a hard top corner bracket from paddock spares. And unless I'm being really thick, I can't seem to fit the bloody thing! Think I have the corner bracket in the right place and have the belt reel attached but that's about as far as I've got.

I've looked everywhere for detailed photographic diagrams, but to no avail.

I want to be absolutely sure that I'm doing it right as it gonna be for my 2 year olds car seat! So can bodge it together.

I have stupidly promised him he can come with me for the first time to the dump tomorrow, so please HELP ASAP!!!

HUGE thanks in advance

I have recently done that job and can send some photos that may help.
It took a little bit of thinking but quite simple in the end.

Send me your email address as I can't seem to upload the images from my iPad.

did you get this sorted in the end as I want to install an inertia seat belt into my series 3. Which bits did you buy etc?
