Need some tips on how to remove the quarter panel mouldings. Just unbolt the nuts and use tools and carfully bend it or does anyone have another way? Do I need to remove the rear convertible panels?

 

There is a clip at each end that has a threaded post. You can get to the one in the trunk easily. The forward one will require that you remove the interior panel. All the center clips are plastic that just pop into slots. Those just need to be carefully pried out.

 

VERY CAREFULLY

They are like gold

 

True,
FWIW All the plastic clips can also be pushed out from the inside with the exception of those right over the wheel. Those are just very hard to get behind

good luck. Like Jamesbo said. The moldings are stupid expensive to replace.

 

Is this the correct quarter molding clips 1969 442/Cutlass convertible?
I can’t get the clips to slide in to the molding, looks like the clip is too high?

 

those are the correct repro clips and they don’t sit flush worth a crap. I ended up only using those where I couldn’t access the back (over the rear wheel). Everywhere else I filed the slotted holes slightly larger in the center and used the same clips as the front fender.

 

Ok “just like original” yeah right!?
Can you please take a picture on your car where you used these clips? Is it a big gap between molding and panel?

 

I did the same thing. I could not get those reproduction clips to work either.

 

Those clips you have are not going to get the moldings flush to the body. I tried them and even took a razor blade to try to shave them down and still would not work. this is what Ally is talking about doing

 

well I saw the issues with molding clips I found a set of nos so they said on eBay does anyone know the gm part number of original clips? This is worrisome that the repo clips suck and there’s about 4 push in clips each side you must use? Hopefully I can find real ( gm) marked clips or I wasn’t bs’d on the new stick I just grabbed lol

 

I’m thinking about doing the same but I wanted to know how it would look over the rear wheels where you can’t use threaded clips?

 

This topic brings back some bad memories. Be aware there are at least two, maybe more, suppliers of these clips and you have to find the RIGHT ones to have success. The wrong ones - like the first picture above - will ruin your day fast. Ask me how I know!
When painting my car a few years ago I got the clips from Fusick. They looked like the original ones that came off the car but when my painter tried using them, things went bad - same as described above. Also, the originals have tiny o-rings around the 'tooth' to seal the hole against water. I don't think any of the reproductions come with the o-rings.
After the first failed attempt, my painter contacted Fusick and they sent him another packet of the clips. This time, they looked pretty much exactly like the originals. Much better than the first batch I got from the catalog. My painter had to use a tiny bit of silicone on each 'tooth' for sealing but other than that, the clips fit good and the molding sits nice and flush.
I wish I had more information to share regarding the 'good' vs. 'bad'. In a photograph they looked the same but in your hand, it was obvious one would work and the other never would.

 

I had the same experience as you. For the ones that I had to use the slotted hole fasteners, I ended up re-using originals. I still have a bad full of those useless clips with the o-rings
