B-Pillar Belt Mount

[Tassie]

Hi all

 

I’m after details on the upper b-pillar mount that was fitted to later models with retractable seat belts.

 

i assume that a reinforcing plate was fitted inside the pillar.

 

Does anyone have photos etc?

 

thanks.

Here you go.  Looks like the threaded plate inside the B pillar is about 3/8" thick.

Forgot to say, this is on a 1973 2002...

FYI squarelights have two B-pillar mounts, one above the other, to accommodate drivers of different heights, so if yours doesn't fit correctly, you can move the mounting bolt to the other hole.  That's what the black plastic plug is covering.

I have used an aftermarket plate like this one to retrofit the mounting point.  I cut a slot in the pillar and slide the anchor plate inside, affixed it with rivets and then welded it in place.

Thanks for the lead. They have all sorts of good stuff for retrofitting belts.

Thanks guys.  I was thinking of making some similar reinforcing plates, but worried by the available space inside the pillar.  Probably only room for a 3/4” by 4” plate. 

 

Any thoughts on tapping 1/4” plate vs welding a nut to thinner plate?

I got these from a FAQ'r who was cutting up a car.  I need these for my 69.

Here is how I cut the pillar to accommodate the brackets.  As you can tell from Jim's photos, there is only a little room inside of the pillar to fit the bracket. You have to first cut a significant amount off of both sides of the bracket.   If you then cut a slot with a hole for the nut, you can just get the bracket inside to pull it back against the inside skin of the pillar.  I put a nut on a seat belt bolt and then tightened it down enough to drill holes for the temporary rivets.  You can then weld up the slot and finish it so it looks original if you want to.

Thanks guys, those pics are awesome!

 

Time to break out the grinder and welder....  ?

hi all,

 

I am looking to put front retractor belts in my 1970 '02 using a similar bracket method to halboyles on the B Pillar as i am fitting Recaro seats that sit a bit taller than the original seat, so I want to mount the belt higher than my shoulder like in every car since 1970!

 

I thought about cutting out about 100mm of the inner pillar section, drilling the hole, then welding in the bracket in the inner side, then plug and butt welding that inner piece back into the pillar. (doing a full sandblast & respray so not perturbed by this job destroying the duco!).

 

Question I have - does anyone have the measurement of where the factory bolt hole is located on the B Pillar that they can provide???

 

Thanks in advance

I don't have the measurement anymore, but here's a visual, photo snapped when we did it to my early '71 02.

thanks for the pic - that gives me a good reference point and turns out to be quite a bit higher that I had guessed or marked up on mine (at about 220mm lower than that top elongated slot). Seems like I can move it up a bit further still!

 

did you cut the inner pillar out, put the plate/nut in, then stitch it back in (years ago I remember seeing someone on this forum doing it that way)?

[Rodolfo Lasparri]

Its 24cm from here to dead center of the hole - did this on my '69. Mocked on Andrew's image.

thank you all!
