Outer headlight query
Outer headlight query
The rubber boot to the rear of the headlight that is held in by 2 semi circular riveted metal plates. Is there a source for these or plastic or some other alternative for retaining the rubber boot? I have new plastic bowls to fit but would still like to fit the rubber protection for the back of the headlight bowl or does conventional wisdom believe they are just worse at trapping moisture and dirt

Re: Outer headlight query
I have a pair of these, part of a batch made by Mark (SprintMWU773V) a couple of years ago. I'm still in 2 minds over whether to use them or not, for the reason you have stated, they seem like another rust trap to me! But the area where they fit is extremely difficult to get at for cleaning, even if you screw the lamps and mounting panel in instead of welding/rivetting as was originally done. (which is what I will be doing) So they might get fitted anyway!

They look just the ticket. It is an awkward area for sure

Re: Outer headlight query
What we really need is some proper wheel arch mudguards in plastic to protect ALL that area. I might look into scrapyard choices, see if I can find something that is close enough to fit with minimal modification!

Re: Outer headlight query
Looking at mine it looks as if the plastic mushield has done it's job, I thought that the water ingress was probably from the front. If you think about the car driving down a motorway in the rain that area is right in the firing line. Although the bowl is sealed to the outer retaining panel and inner valence water, muck, salt etc must creep in from around the outer panel and just pool there, then over time the inevitable happens.
I wondered if a drain hole at the bottom of the eyebrow would help, just where it meets the inner valence.
Just a thought!

Re: Outer headlight query
Yes but the nasty little afterthought of a plastic mudshield behind the headlight (which is only on post 76 cars) just transfers the rot point from the front of the wing to 4" back! Admittedly, that area of the wing is easier to repair than the front corner above the eyebrow - but still not ideal! A nice drain hole in the valance (it's not the eyebrow here) below the outer headlight can't hurt, I think I will incorporate that in mine!James467 wrote:Looking at mine it looks as if the plastic mushield has done it's job, I thought that the water ingress was probably from the front.

Thinking about the seal that is the root of the OP, I can't actually see what good it is, since there is water and maybe mud on both sides of it and on later cars with the tacky mudshield, water on at least one side and probably both. And with plastic headlamp bowls, it's purpose is even more moot.
I reckon what is needed is a full arch shield, some decent drainage around the lights, the facility to easily remove the headlamp support panel with lamps to clean behind and finally lots of lovely Hammerite or similar coating both sides of the inner front panel, eyebrow etc. This is what I am going to aim for on mine, which will effectively be a daily driver so it'll need all the help it can get. I certainly don't want to be putting ANOTHER front end on it in 10 years time, i'll be over 70 by then!

Re: Outer headlight query
Completely agreed!
So as we know the headlamp support is held on by 4 spot welds and a tack weld. If these were replaced with some locating screws and captive nuts on the centre support bit (the outer tack isnt really needed) then all that needs to happen is to remove the trim panel and grille then 4 bolts/screws and the whole unit should come out nicely. Does that make any sense at all!?
This would be especially useful if you have a halogen conversion as you'd get easy access to the bulbs.

Re: Outer headlight query
Makes perfect sense to me! I guess rivnuts or similar would be ideal to secure the panel, 2 at the inner mounts 1 on the centre and 1 at the eyebrow should do nicely, though I am inclined to use the self drilling tapping bolts I used to secure my GRP wings whilst the Tiger Seal set! You'd only get to the inner bulbs easily, unless you cut the back out of the outer bowls, something I'm a bit loath to do as water can still get in the front, but bulb access is easy enough anyway, at least you don't have to take a wheel off to do it like a lot of moderns require!James467 wrote:Completely agreed!

The other beauty of bolting over welding is that you can get to everything to give it a thorough painting as you build it up and don't have to worry about the weld burning the paint off places you can't get to to repaint, seems like a win-win to me. I shall also be using self tappers and spire nuts to hold the lamps into the support panel rather than the el-cheapo pop rivets the factory used and the same for the grille fixing.
The way the factory built these cars is, after all, not the BEST way, merely the cheapest! If a little lateral thinking and the benefit of hindsight can improve the cars survival chances, i'm all for it and blow originality (not that I'M exactly bothered about that anyway

Re: Outer headlight query
Came across this thread as I was searching for some information on the headlamp panels. Can someone explain where the self tapping screws are best located? Also, once I'm replacing the corroded metal bowls with plastic ones, do I need the seal at the back (the rings are crumbled....)?

Re: Outer headlight query
I've left them out on the 1850 I'm restoring, as for the underside I'm using the original slash guards and copious amounts of a good quality flexible underseal.
Some people are like Slinky's, they serve no real purpose in life but bring a smile to your face when you push them down the stairs.
Re: Outer headlight query
How did you fit the plastic rings? They don't look like rivets.
