330 GTC - Rubber pad under door sill metal threshold

Kevin - PM me your email ref this topic

 

While I don’t have answers to your specific questions nor am I very familiar with many of the minor(?) GTC details, there appears to be a potentially inaccurate description of one in the text above the photos of screen shot of the “GTC Configuration Guide”.

 

I didn't notice this rubber piece on my 365 either, but looking at the picture on the right it seems to me that the rubber is ribbed and not flat. It could just be a thin frame for the aluminum threshold that eventually fall off as it dries and deteriorates. Just my observation.

 

Just so that those who really wish to learn can do their own homework or at least think whether the presented statement makes sense, instead of blindly relying on posted/printed material in front of the them.
Internet forums and experts in them seem to present enough inaccurate or misleading information as it is already.

Besides, it has ever been my intention to try spoon feed anyone with something as controversial as production details/features on 50+ year old Ferraris, especially on something I just suspect being “potentially inaccurate” and don’t have substantial firsthand experience with.

 

OK, apparently I ruffled some feathers, but if you don’t mind, I’d like to ask a couple of question and maybe I can learn something.
What is the (originally used) material and finish of the “ribbed threshold strip” shown in the reference pictures ?
And is the material and its finish same in all or most GTCs ?

 

those rubbers look same like those from the fiat 124 spider from 1967 until 1984

 

Romano - if this is true, can u post a link to the part supplier that may have these so we can assess the correctness?

Thank you for info!

 

The material in all GTC's is similar to other fiat and alfa related mid 60's cars - the size , width and length vary as well as the holes for mounting. Generally they are polished aluminum as the finish - some restored cars are having them chromed due to the scratches in the aluminum that impact the overall look and finish. Hi impact visible area when you open the door.

The questioned rubber piece underneath is a vinyl strip, with a beaded edge heat sealed to the end of the vinyl strip.

Unfortunately i did not take pics of this when we were in assembly mode but here are the finish products - this is orig vinyl beaded strip against a refinished chromed door sill plate that the OP was asking about.

will try to find out

 

just called my distributor for fiat parts and he told me those rubbers you get in a hardware store on a role and you may cut how much you need. but in the 2 big hardwarestores in my area they not have

you may go to an upholstery shop or saddler and ask for profile rubber

what about this:

you may google a little

 

The door sill underlayment is not the issue as there are solutions for this, the correct end is unique as it is heat sealed to the underlayment. It has a small bead on the end - that is what you see in the pics. There are some solutions to this as well depending on your level of correctness for your car. I would some mat material that is has a rounded corrugated top layer that once sliced and trimmed, could work.

 

If I/we assume above assessment is correct and others are able/willing to agree with it, referring “them” as “chrome, ribbed threshold strip” would be as inaccurate or misleading as referring a “Parking brake” as an “E- or Emergency brake”, latter being a term countless people, even many so-called “car guys” commonly and persistently seem to use both in verbal or written expression.

Or like another, commonly used, misleading term of “chrome” in references to (brushed or polished) stainless steel or (anodized) aluminum exterior moldings found surrounding windshields, rear windows and/or used as coach work adornments on countless (vintage) automobiles.

@fasthound - While my intention wasn’t to insult anybody, I wish to apologize for such unintended consequence.
My point is/was that using inaccurate/misleading technical terminology, especially in publication intended as an authenticity guide/reference, can also have unintended consequences, considering that at least I can easily imagine some poor soul in the reading that reference description and mistakenly become convinced the “chrome, ribbed threshold strip(s)” should be chrome plated rather than just polished (or perhaps anodized ?) aluminum, potentially causing (unexpected ?) deductions/disagreement during experienced/knowledgeable judging* or its aftermath.
