At the prompting of a great PFF member, thanks Mister, I give you a post to help you all determine the difference between CJB coded T-Tops and the 84-88 NON-CJB Fieros. Any T-Top from a 1984-1987 Fiero is a NON-CJB. A 1988 Fiero maybe a CJB Fiero if it has the RPO code CJB on the options sticker under the hood. All other 1988 Fieros without the CJB RPO code also fall into the NON-CJB category. I know of at least one other t-top that I've seen on a Fiero that differs from all pictures I will post right now, but that is a rarity that I have only seen one of, so the odds of anyone having that particular set of tops is slim to nil. Without further ado, I bring you a little introduction to the difference between CJB and non-CJB t-tops. With a couple pictures of the glass seals so you can tell the difference.
88 CJB glass, note the Cars & Concepts logo on it:

This is a non-CJB glass, it also has a Cars & Concepts log on it:

This is the union of the CJB glass seal and the CJB B-pillar seal:

This is the union of the CJB glass seal and the CJB A-pillar seal:

This is the union of a NON-cjb glass seal to my CJB B-pillar seal: (note the shallower angle of the glass seal, the non-cjb door seals are bigger than CJB to fill in that gap)

This is the union of a NON-cjb glass seal to my CJB A-pillar seal:

This is the B-pillar side of my CJB glass seal:

This is the B-pillar side of a NON-cjb glass seal:

This is the A-pillar side of my CJB glass seal:

This is the A-pillar side of a NON-cjb glass seal: (Note the different shape of the front of the seal)

This is the start of the CJB door seal, just below the A-pillar:

This is the CJB door seal at the peak of the A-pilllar:

This is the CJB door seal at the peak of the B-pillar:

This is the CJB door seal at the midpoint of the B-pillar

Ok, everyone knowledgeable about T-tops check these out, please let me know if any of this information is wrong. My car does have the CJB code, and I'm going under the assumption that the door seals and driver's side glass are actually CJB. That is what was passed down to me when I bought car. Passenger side glass is different because original owner broke passenger top. To my knowledge, the passenger side glass is non-CJB.
Hope this helps everyone out.

Would anybody with a Non-CJB coded car like to post some pictures of their seals for others to reference the difference between CJB and Non-CJB t-tops? Thanks to anyone whom does.

I am in the process of painting the trim and replacing the locks, but I can take the pics of the non-cjb body seals. I will take pics of the glass seals once they are finished.

To me, the easiest way to tell if you have CJB or Non-CJB is to look at the seal on the car. The NON-CJB seals have a separate rubber trim piece that goes around the headliner area. It clips down. The CJB seals have this integrated directly into the seal itself. Pic below is NON-CJB rear seal. I pulled the rubber strip out a bit to show you:

Below: Non-CJB rear. Rubber trim strip pulled for you to see:



Below: Non-CJB read with rubber strip pushed back in place:

For some reason, PIP started asking for a name/password, so I can't post anymore pics. No clue why..

Thank you very much smartaxel. + for you. I have personally never seen a non-cjb car in person so trying to explain the difference to other members hasn't always been clear as crystal. Hopefully this little thread will help others when they are looking to purchase t-top kits or glass like from ebay. I would have loved to have this before I bought my ebay glass; now I have to swap glass seals to the new glass panel... Not looking forward to that.

All t-top glass is the same, CJB or Non-CJB. The only difference is the roof and glass weather strips.

Whats CJB stand for? I have an 88GT t top cjb rpo code. I would love to have new seals for it especially the ones that go across the roof(side to side) in front and behind the glass. I'm not in that phase of my project yet so I hope they are some around when I get to it.

So... To dumb things down for myself...

CJB = "stock/factory" basically? (Technically no T-Top is stock though, correct?)
