Hi,

 

 

Can somebody post a picture from the mounting point from the seat belt retractor in the rear luggage bin? (next to the rearseat)

 

I am rebuilding a mini from 1973 and can't find a sturdy mounting point.

There is drilled a hole in the underside/side of the bin, but if I mount it there it won't be strong enough in case of a colision because the side of the luggage bin is just sheet metal.

And 2nd; if I mount it there the seat belt will rotate with 90 degrees before it goes thru the rectangular hole on top of the luggage bin. The belt will then quickly wear out and get stuck regularly.

So I'm not going to mount it that way.

 

Unfortunately there is no other mounting point (welded nut) to fasten the retractor of the front seat belt.

 

Hope someone can give me a good description or even better post a picture from the mounting point which is (normally) original there.

 

Thanks in advance.

 

 

Kind regards,

Ingmar (from the Netherlands)

Here you go. They do fit to the rear bins, that's the normal position, but notice the strengthening spot welded to the bin.

Thank you very much Panky.

 

Ok, I already paint the car, so that's a little problem.

I can drill the hole but I have to see how I fasten the plate to strengthen the area.

Maybe I can glue a 2 or 3 mm plate behind it with windshield adhesive with enough surface, so I don't have to weld it and damage the paint work.

Hi,

That's the newer mounting point.

Back in 1973 bolted to the side of the companion box was considered a suitable mounting point.

Cheers  :proud:

A MK3 mini does not have the same mount as the mk4 onwards type. Yours will be like mine

After i modified mine

Now i added a thick doubler reinforcement plate and added plenty of larger plug welds all round when i refitted my companion bins. Will it be as strong as the later style of mounts, i don't know but i want the original look

I wouldn't use the bin unless it's reinforced. I had a '74 that had the reel on the same mounting as the end or the belt.

I have the same holes in the bin as on this picture, but they aren't reinforced, so in case of a colision it won't be very safe.

I have build an tuned motor and the car will be used on the race track occasionally.

So if it goes wrong it's a reassurance that the seat belts are safe.

 

 

And if you mount the retractor on the side of the bin, the belt will twist for 90 degrees en doesn't go straight thru the rectangular holes which are on top of the bin.

So I don't think it is the best way to mount the retractor on that spot.

Here are the the pics from the bin of the mini.

There is no reinforcement behind the holes, it is just sheet metal with holes in it.

IIRC yours mount outside of the bin and the rectangle holes are actually for ashtrays. which is what I was thinking from your comment about some rectangular holes.

Aha, alright!

Yes, that make sense! Never thought about that.

I thought they were always mount inside of the bin.

 

Sort of out of the box (bin) thinking   :D

 

Thank you Nicklouse.

 

So the rectangular holes are for ashtrays.

I thought is was only there to hide the retractor of the seat belt.

I prefer to make the car original as possible so I will mount the retractor outside of the bin en strengthen it with a 2 mm plate.

i have seen belts come out of them as well but i dont think they were original like that. and again your mounting may not be original but aftermarket. as your car age did not need inertia belts.
