So I am in the middle of some interior work and have a few questions about where to get some items. Removed the old carpet, scraped out the seam sealer which was falling apart, wire brushed all of the surface rust, wiped it down with acetone and am ready to prime and paint the floor this weekend. After installing the floor plugs I want to put down some of the thick padding and possibly purchase and install a new loop carpet. Question 1 - is there a preformed/molded carpet pad for my convertible and if so who has it? Or am I just buying the bulk material and laying it down the best I can? If so, any recommendations on a good brand/store to get it from? Question 2 - I have called multiple stores (I.e. stock interiors as well as legendary auto) and have been told that either their molded carpets only for the 2 door automatic COUPE and not the convertible or that they don’t have enough info in their computer systems to verify that their carpet will fit a convertible 300. Where can I get a quality molded carpet and be reassured it will fit my convertible and does anyone with any experience with this subject know why the carpet for the coupe won’t fit the convertible? Thanks again in advance!

I was going to recommend ACC. Flooring for a 1969 Chrysler 300 | Auto Custom Carpets
But they show nothing for the convertible. I am not sure what the difference is between the hardtop and convertible for carpet. They have the hardtop. I forgot now who actually makes the carpet. I think there is really only one supplier left in NA.
 
There is only one company making molded carpet and that is ACC. That is what they all sell... Doesn't really matter.
 
It could well be that the differences are in the rear seat area, on the sides? Possibly trimming the 2dr hardtop carpet a bit back there? Seems like there have been a few threads over the past few years on carpets for the Fuselage cars in here? With pictures.

In many cases, the jute padding would be glued to the backside of the carpet, OEM, as what you removed. You can buy bulk-roll jute of the correct thickness to replace it. Cut and place to fit. Would be a good time to spray some LizzardSkin or stick some DynaMat (or similar) squares on that bare floorpan. See if the carpet vendor has the jute on the back of their carpet.

Did you replace the seam sealer you removed??? Need to, I suspect.

Just some thoughts,

After cleaning, prepping and sealing the floor in my 69 300 convertible I applied a insulated sound deadener similar to dinomax but much less expensive. Then a ACC carpet. Hardtop and convertible use the same carpet.
The sound deadener made a huge difference in both reducing road noise and heat transfer through the floor. It is usually available on ebay.

My main concern is that once the Dynamat is down, if there’s ever a issue with the pan in the future where somempart needs to be welded, accessed, etc, it’s gonna be a ***** trying to get that Dynamat off. The floor is in real good shape except for a handful of pinholes in the passenger side footwell. What’s everyone’s take on this? Thanks again! Also, anyone ever hear of filling the floorpan grooves with the seam sealer so that the Dynamat lays flat and doesn’t have to be pushed into the grooves? Just a thought. Thanks all!

Fix it now before you put the sound deadener down.

I used the same stuff Will did. Much cheaper than Dynamat and I'm sure you won't notice any difference, especially in a convertible, over the dynamat.

Quick search gave me this... You may find it cheaper with more searching.

I used a heat gun to warm the floor pan as I installed the "Fat Mat" and a roller to push the mat into the recessed areas. I like seeing the recessed areas, but that's just me. Once installed the mat acts as a membrane seal on the floor pans and likely will never need to be removed if the pans are prepped correctly.
A little extra expense and effort, but well worth it.
 
A J-roller, like they use on laminate countertops, is really handy for rolling down the mat. $15 or so at your local Home Depot/Lowes. The handle end is also just about perfect size to push it down into the recesses.

Dave I’ll respond to your message to me on this thread since several guys have echoed my answer- first I found this tag of a company attached to my old carpet upon removal see pic of tag-
With research I found that this company was a BIG supplier to auto makers for A LOT of years - they finally called it quits in the 1980s. Along comes ACC and buys up all the templates/ codes of their records. Long story short their carpets are molded and fit correctly— that is until the coupe carpet is used in the convertible: see picsView attachment 459346View attachment 459347
The convertible needs just a bit more between the seat and side panels- you’ll need to trim a bit off the door sills so you could use that - I chose to live with it since my original carpet is still under the replacement carpet and aside from close up pics is unnoticeable— until now that is

I went thru this w my car, a 66 polara ragtop. All the suppliers seem to get their carpet from one or two manufacturers so it all appears to be much the same, the carpet will not fit the convertible. I got carpet for a 2 door hardtop and wanted to try to install it myself but ended up going to an interior shop. This issue, as I was told, is the extra bracing for the convertible that goes from side to side under the rear seat causes some fitting issues. If you order it tell them not to trim off the exxess, you may need it. Mine fits pretty good, there are a few wrinkles but not bad. I hope this helps

I do not see any differences in the floors on the 69, having (dad) a convertible and a 4-door sedan both 69s
These are the 4-door

Almost identical to mine.

I used tar rope to hold the sections down when it wanted to bubble up from the floor

What did you use as the gray primer? And how did you prep the pan before hand? I have wire wheeled all of the rust and seam sealer off. The wire brush seems to have “spread” the goo out over the surface of the pan. I’m going to use acetone to try and remove the film before painting. Any other suggestions?
