Bulkhead door seals

[Nobbysr]

Hi Folks

1.  Am in thr process of finishing my Tr3A rebuild and have  looked at fitting the rubber seals that clip into the holes in the bulkhead,   but on both sides of the car the top hole appears to be too big for for the clips
2. so my question is, Is the top hole a drain hole and the start of seal  is at the smaller hole not the first large hole hole???

 kind regards

Steve

That just looks like someone has tried to use a different clip in the hole and in consequence enlarged the hole, the seal should finish beneath the capping once that’s fitted,

Depends how original you want to be, but I went for a self adhesive seal, now been in place for 7 years and does away with those horrible metal clips that damage the paint.

  I like this idea though the ends should be tucked under the dash capping IMHO

It does look that the seal would cover the top hole . i prefer to use the cips  and original seals as the rest of the car is original

Correct, same with the draft excluder.

40+ years in polymer science and technology, much of that in coatings, has made the broad class of silicones, including RTV, one of my least favorite polymers.  They get everywhere — especially silicone oils and defoamers — and can foul up adhesion to surfaces  

Perhaps a rubber plug or some butyl rubber dum dum as an alternative?

I like the sentiment, however the adhesive seal does work extremely well and if you use the car you don’t end up with rusty clips and eventually rusty holes from the clips fretting the paint holes.

Didn`t know how to finish the draft excluder at the time,  I did try to bend the self adhesive seal up under there but it wouldn`t conform nicely with the acute corner so ended up just fitting as shown.
