Rear quarter trim

I have some original chrome/rubber rear quarter trims. Fitting them to the rear quarters, they dont fit right up to the rear reflectors. Is there a SWB version that is shorter than a LWB version or am i just not fitting them correctly?

Do you mean the rubber filler that is sandwiched between the rear wing lower edge and the top of the quarter bumper?
I thought they were all compressible rubber, no chrome strip.

My filler rubber strips are flush with the wing edge and run under the rear light unit up to the outside face of the chrome bumper ('73T), like this picture.
Sorry if I have mis-understood your question.

a photo from me would have helped but i am not at home this week....

So using your photo for reference, am talking about the chrome and rubber bump strip in the middle of the rear quarter.

In your photo, it goes from quite close to the front end of the rear lower quarter and butts up flush to the square bosch reflector at the back.

For the trim pieces i have, and both are the same, in order to be flush to the square reflector, the fixed front attaching pin (integral to the rubber bullnose) wont line up with any of the mounting holes on the panel. If i fit the front pin into one of the mounting holes, there is a 1cm gap at the back between the square reflector and the end of the chrome/rubber trim. I cant move the reflector enough as it has mounting holes rather than slots, as is the mounting hole for the fixed pin in the rubber piece.......

Both the trim and the panel are original porsche (although i bought the trim pieces separately) so am not entirely sure where i am going wrong. It is almost like my trim pieces are too short....hence the original quesiton, are there shorter versions out there, e.g. for the SWB?

There are SWB & LWB versions but the differences are quite obvious - I don't think you could get them mixed up.

The rubber insert does shrink over time so it may be that if your trims/rubbers are the originals then that is the problem.

Don’t the fixing bolts on the rear of the anodised aluminum trim slide up and down in the channel so that they line up with the holes in the quarter panel with the trim in the correct location butted up to the reflector?

Yes but the pre-formed shape (curvature) of the anodised trim means that there's little leeway as to how they can be fitted.

also, the rubber is in 2 parts, the straight bit and the short (3 inch long) bull nose rounded end. The bull nose end has the fixing pin mounted in the rubber so there is no adjustment. It simply fits in a round hole in the panel (not the slot type for the adjustable fixing bolts). If i tit it in the mounting hole, he strip isnt long enough to meet the reflector

probably easier if i post some photos at the weekend when i am home

Totally with you now.
I've just re-mounted my original '73 parts to my original bumpers.
All the rubbers are stock and '73 and certainly do shrink.
Mine are about 6mm short.

The bull-nose moulding is glued to the extruded rubber moulding and the stud is fixed so setting the position, mine fit great, the orange car pic is off Google.

I'm not sure all these parts fit 'intimately' together when new, I would expect some gaps.

One of the bull nose sections on the front bumper also has a sliding captive stud on my car as the rubber moulding does not pull down totally flat, it needed some help from the extra stud and slo a new hol to allow it to pass through the bumper itself (fibre glass).

It is to your advantage to have all the captive studs freely moving in the alum extrusion and to play with pulling the stud up tight (ish) to allow the whole bumper rubbing strip to seat down.
I hand tightened mine from the static bull nose stud and bought the rest down progressively to minimise the gap to the reflector body moulding (mine are also original 73 to the car).
worked better one side than the other. There is also some lateral movement to be used in the reflector mounting studs, but not much (3mm?)

I did not clinch the nuts down too tight, nipped them screw driver tight and locked the nuts using clear Humbrol varnish to stop any shaking free before mounting on the car.

This is a picture of my car during a recent re-paint/re-assemble.
Look closely and you can see the shrinkage of the bumper/alum channel seal against the reflector. (I hope!)

Hope this helps.
