This Targa top kit was made back in the 1980's by a company called AutoDyne but I have yet to see one that's been installed. The literature claims that it uses a one piece detachable roof section with frame reinforcements. The top piece reportedly is stored on the baggage rack and when installed clamps securely to the top of the windshield and the rear roof section. It looks pretty nice in the picture.
I just wonder how many kits were sold and installed.

Seems like there was a Targa section of some sort at the Fiero Factory, laying in the showroom, but I have no idea what became of it.
Also, at least one person on the forum had a complete - and driving - targa conversion, done on a notchie.

Corson and B&B Customs made them back in the day.

This is a really old post, and the car was rescued after sitting for 5+ years, so it was likely converted prior to 1996.

This is the Corson kit:



This is the B&B Kit



Bloozberry had a cool solution w/o compromising the chassis structure. Enlarge the stock fiero sunroof opening and use a removal targa panel:

Interesting info here. If I were to install a Targa top I would definitely install a subframe that ties in front and uniframe members like is done on a convertible. If the price was two grand back in the day, that would be like 4 grand today. Certainly very expensive for basically a fiberglass panel, the windshield header, the reinforcements and some attaching hardware. While this is a novel idea the cost may not be worth the result. Around that time I purchased a complete retractable Califrornia Convertible kit for $1800 including the top.

I had one of these kits way back in the day, on an 85 GT

Looks cool, but squeaks and rattles, lots of body flex, hard time closing the doors, despite the frames supports that were meant to add rigidity. Definitely would not recommend

I believe that the one in Ed's showroom was the Corson kit.

Edit - I was very wrong about my comment regarding the B&B project, but I still believe it was never completely developed. I have never seen one in the wild.

Well l remember these kits from back in the day. I had considered them.

Roof storage is a problem if you don’t have a luggage rack. Also the flex is horrible.

I went with the C&C t top on my car. The TTop cars have a little more flex than stock but nothing like the targa.

Chassis reinforcement helps but it is still not enough.

Few were sold and very few survived.

The space frame was just not designed for a targa. The T top either but C&C did a good job of coming up with an acceptable solution that would pass GM’s approval not to void the warranty.

>>>>>>> That and price is why they probably sold poorly. A fold-able soft top that could fit in the trunk would have been far better. If you didn't have the luggage rack this Targa kit is useless. Rain can happen at any time.

>>>>>>>Absolutely, the center roof support will undoubtedly help
Chassis reinforcement helps but it is still not enough.
>>>>>>>I believe that the Targa top conversion would need the welded full under-frame Brisa Convertibe design to work. That under-frame is welded from 1" x 3" steel channel. It welds to the front cross-member, the uni-body front rails, then goes back to attach to the rear frame where the cradle mounts are and also near the jack points. Finally there is a bolted in piece that ties in right and left sides of the frame channels, in order to facilitate gas tank removal if needed.
Few were sold and very few survived.
>>>>>>>I have been to many Fiero events and have never seen one of these. Perhaps the resulting bent frames caused many if not most of these cars to be scrapped.

A one piece top is better for resisting water penetration but a two piece solid top like T-tops would be a way to solve the storage issue without the problems of actual T-tops with their specific and hard to source T-top only parts. That was always my thought. Seems like the Solstice coupe (which is a targa) has an issue of storage of the top. A two piece design would address that issue. A fabric take along top would too. Leave the hard top at home and stow the fabric one for just in case.

Chester and his Dirty Rat vehicle had a number of issues when he tried to get a functional targa top on his show car. I do not think that he was ever really satisfied with the results.

Pretty sure Doc John did one of those on his 328 kit. If I recall he did have to correct a bad case of door sag by installing a x-brace to firm things up. It's ashamed his excellent history of ownership was ruined by the photo bucket money grab a few years back.

He parted a lot of it out, but someone did buy the chassis with the intent on fixing it.
New owner says he made some progress, but then disappeared.

I am the person who ended up with the Rat engine and it needed some mods to work better. Fiero Guru did the install and mod work and the engine turned out nice. Now if I could only finish the project Mera that currently has this engine. Maybe in the next year or two if my other car ever gets out of the paint shop.

There were several chassis brace items offered in the 80’s. All were not good and many had drawbacks. Hence few were sold. The way to make the chassis is difficult to retrofit correctly.

The TTop as long as you had good seals it did not leak. If it did leak generally it was where the door seals were on the top and glass of the door.

T-top car and their notorious leaks, from all makers, are all described exactly the same way.
