The two holes on the rear bumper are meshed on my car.
It is not original, isn't it?

No but looking at the picture someone's made a good job of it, did they do the front too?

No, they did not. But there are a lot of cracks on the front bumper instead of it...   :(

The rear bumper looks quite good, but others... all repairs are awful...
The car has a devil exhaust. On the right side a small piece was removed and it is not so nice job.

No not original, but looking at the holes above the exhaust is also no nice view.

Looks a lot better, but that is ofcourse personal taste.

All of you, who modify the rear bumper by installing grills in the two openings, should be aware that the openings are at a point where the vacuum behind the car is greatest.

I believe they suck hot air from the top of the engine compartment and out the back. Grills will restrict this airflow and possibly lead to a hotter engine compartment and poorer cooling of the engine. :(

They do look nice, though.  ;D

I was aware of that but so far no cooling problems.
I have the Ferrarie hood with 2 extra airducts tjhat give some extra.
Also I have a expansion bottle that holds 1 litre less coolant.
It all works without problems.
Coolant stays always below 95 degree C.

Yes Jon, you are right. The engine-bay, the glasfibre-panel at the bottom-side and the outlet in the rear-bumper are created to build a vacuum and pull the hot air out. There is a drawing from Matra existing where it was described. But that was made for high-speed driving and does not work ( and cannnot) by lower speed. The speed of the air flowing at the bottom is needed to create the vacuum. But since we have a speed-limit in the almost countries and our cars are close to be an oldtimer, i don´t think that so many people anymore driving with top-speed ( or close to ).

 ;D Last weekend - 220 km in 1,5 hours... top speed (GPS) 221 km/h at 5600 rews (thanks to longer 5th gear). Who cares about speed limits?  ;)

I think the black spotted grills look much better than mines.
Today I removed them. The adhesive was quite weak... fortunately.

I would like to restore my car almost to the original condition. But the fuel pump will be modified... :) and the colour also. It was corall, the ugliest original colour... (sorry if someone likes it)
Now it is white and I like it.

Another question. The end of the rubber lines beside the rear window are fixed by screws (above the tail lights). Is it original? You can see it in Oetker's photo.

I don't have a clear pic, but as far as I know the T-strip was cutted  to straight end and folded at the edge,.
The screw was behind cover.

You can find this picture at the instruction booklet around page 30

I have it also fixed by small screws, it seems to be original. Don't forget, that some production dates are different in details, often just like this  ;)

Yes, the little screw at the end of the rubber-strip is an original detail.

@ michaltalbot: i had you in my mind, when i wrote that the most Murena-driver won´t drive fast any,more. At first i thought to write between the lines "except michaltalbot", but deleted it before posting, changed it to "not so many people"  and said to myself, i will look in the evening about your comment. ;-) And... it came.....

:-)

In 1981 the screw was invisible, in later years it was as you can see in Oetker's photo.

When we all will be castrated and restricted to blindly accept the speed limits everywhere without using our own brains, than we all could be riding Skoda Fabia 1,2 HTP  :'( At some website here in CZ, we can see which parliamentarian voted for which law, when I saw those 60 years old women and men, who haven't riden more than 100tkm through their whole life - how I have to respect their decisions? Every thing have to be decided by specialized people, but here one woman is doing Minister of health, half a year later she is a Minister of army, etc. They are there only for getting money, and are producing bullshits which I'm not going to respect. Czech Republic is full of nonsenses - there are places, where is allowed to overtake, but I will never overtake there because it is in corner. Than on straight place it is forbidden... Police is measuring speed on 4 lines highway on Sunday noon, but not in front of school at the week. They had to decrease a sound pollution on highway - money for sound barriers were lost on their own accounts so what they did - they rescricted the speed limit from 130km/h to 50km/h - do I have to respect this??? Hope that You'll understand me  ;)

Thanks for all.
The link recommended by JV is very useful.

p.s.: Michaltalbot I understand you. Hungarian politicians are the same or worse... Sometimes I am really ashamed of them...

It's the same everywhere - look at european politics... (http://emoticons.sweb.cz/icq/Smiley23.gif)

Grills have been removed and repair is almost ready. It needs some filler, sanding and a new paint at the end.
Defect was replaced by glass fiber kit (green). To give the form a stock was made of a piece of aluminium plate covered by foil tape to make removal easier. Then it was strengthened by a layer of glass fiber and two layers of epoxy resin on both side. It looks quite good...
Hopefully it will be longlasting. :)

Nice work, Klumzer :)

Good job! Another saved bumper (http://emoticons.sweb.cz/icq/Smiley20.gif)

Thanks, but I was only an "apprentice", my father was the expert. However I could learn a lot. But his name is also the same... :)

My rear panel was held on only by the rivets on the top and underneath with no sealant.

One more question...

What was the original colour of the area between the tail lights underneath the plate? Black or the colour of the car?

I am pretty certain it is matt or satin black but I have sprayed mine the colour of the car.

Today I removed the rear panel. There was some glue at the sides but it was not sticky so it was quite easy.

Now I am busy with the rear fender removal... not so easy...
I started with the left one. About a third of it is loose, the rear part so I am quite optimistic.
If I am not mistaken the applied glues are the same as the glue on the front bumper. The sides (bends) of the bumper are glued with a hard material and the upper line of the rear fender has the same. It is very difficult to remove...
Other parts of the fender are glued with a soft and sticky material which is the same as the glue of the indicator and fog light inserts in the front bumper. It is easy to cut...

I hope I will have some time tomorrow to continue the work. I will share my experience and post some photos.
