Great work, sounds like you do have a plan. Also seems like you have done your research or have seen this stuff before. I don't think you need outside advice like suggested, other then to stick to your plan.

Thanks guys, always happy for advice and I had read one of Dub's posts on fiberglass repair a while back before I started.
Did a few glass repairs when I did the engine bay but certainly no expert.
Just taking it slow as it was a big step to grind away the nice paint and get started on that front corner and chin spoiler.
That front corner was just a tiny crack that lead to a bad glass repair from the past covered in bog.
As I started grinding it out it got bigger and bigger.
More than happy with the repair so far now just need to move on to a few more then finish it ready for paint.
Sounds simple but it won't be :-)

Hi Craig,
There was a thick 'spacer' that was used on the bolt for the bottom of the bumper-ette.
It's there to prevent the bumper-ette from crushing the fiberglass air dam when the bolt is tightened. It fills the 'gap' in the hole in the fiberglass. It also helps save the paint a little.
These have often been lost at some point so you might want to consider using them if you don't have them.
Also the nuts used on the bolts that mount the plastic extension had captured washers on them to help preserve the air dam paint as the bolts are tightened.
Regards,
Alan

That's interesting Alan so the washer was thicker than the fibreglass and stopped the bumperette damaging the paint.
Will need to look at my originals to see if it's there, but I doubt it.
My reproduction black spoiler nuts and bolts don't have the washers as described. That would also mean originally the bolt came through from behind.

So we test fitted the bumper today. That was a bit of a pain to try and get it even and sitting almost correct.
Would love to have a large wood vise so i could twist it a bit to get it perfect but at the end of the day here is where we got.
This corner has a slight drop that i can't get out without possibly twisting the bar. If I let it sit out a bit further at front it can be made a bit better.
We also noticed that the indented fiberglass curve on this side that goes around the end of the bar is not created properly and curves in way tot soon.
I may just reshape the fiberglass curve and edges to make it look straight :-) May be easier to trick the eye than bend the bar.
Compared to my old bar the ends sit in so much closer so its a big improvement already
Tell me what you think and any tips for adjusting the ends.

Looks good Craig. Your right though, it could use a slight twist to get the left side up a bit. I don't think it would take much along the length of the bumper to get the left side even.

May need to make a plate that i can put in the vice then bolt the bar up to it and then try the twist.

With my rear bumpers I cut and re-welded the mounting pads so they both sat straight and even. It's a bit of extra work but worth the effort.

Hi Craig,
I wouldn't be at all happy with the fit. The left side corner looks pretty bad to me.
But what to do about it raises a lot of ugly possibilities.
'Twisting' the bumper may break the chrome and nickel loose from the copper… if not immediately, in the near future. This is because the layer of chrome is so hard and so thin it has very little ability to flex…. and that's what you're asking it to do.
A few questions.
First, do you have photos that show the fit before the 'incident'?
What is the front bumper? An original replaced? A reproduction? If a reproduction, do you know where it came from?
What is the front clip? Is it an original?
And the big one… how far do you want to go with this? It seemed like you were enjoying the car the way it was… do you just want to get back to that point with it?
Regards,
Alan

The front corner was not damaged in the incident.
I decided to correct a couple of minor cracks while the other paint was being done and found a heap of body filler.
However the front corner had been replaced at some time in the cars life. Not that well from what I have found here and in the engine bay where I needed to remake the inner guard closer to what was originally there.
The old bar sat level but both sides stuck out way more than the new one.
I want to get it sitting level on the end but I don't want to boil the ocean in doing it..
This bar is one of the paragon ones so should be fairly good.

The guard had been replaced from above the centre of the wheel to the front corner and part of the front apron.
The front corner where the bar bolts had a lot of body filler. Also the small bracket thar goes against the inner glass for the corner bolt was embedded in the glass !!
Also not sure what year corner was used as it has slight different contours.
After I ground that out and glassed it up I think it is fairly strong.
But it only takes it being out by a bit for alignment issues.
I think it is slightly wider than it should be but not by much.
The panel looks ok to the eye it's just if u measure it all you find the differences.
I don't want to do major panel work to fix it and would prefer to finess the the bar brackets etc to get closer.
The old bar must have been bent a bit to fit and that's why the ends were not snug.
I will keep working it.

A nights sleep and try again.
By loosening the corner and shimming the top ends I can get it better
This means I have 1-2 mmm more gap but I will experiment a bit more when i get back from a few days away.
Hopefully means i can reshape the pad with fiberglass to get it sit correct and not kick down.
Before
After
I may well still reshape the fiberglass curve at the end of the bar to match the other side.
Alan i also checked the other side and it still has bonding strips etc so I trust its contours more.

Out of interest how much for and aft movement is available in the center bumper bracket ?
I have not moved it from the original spot yet but putting it back a few mm's may be worth trying as well.

Hi Craig,
Remember although the center bumper bracket has some built in adjustment the front crossmember it bolts to has some adjustment too.
The front cross member can be 'tipped' too because of it's attachment to the frame rail extensions.
This can affect the bracket's angle when it meets the center of the bumper.
There are SO many fact actors that affect the fit of the bumper it's pretty difficult to know just what to look at.

Alan
