Two piece prototype Collins and Aikman Dura hardtop

Starting a new thread here regarding this unique top i just acquired thanks to Choptop's FB link and some gentle prodding from 4501Safari (Richard).

Let start with the information from the seller.
-Seller's company specializes in liquidating industrial warehouse when companies go bankrupt.
-Around '08 or '09 they were contracted to liquidate 17 of the Collins and Aikman Factories. Two of those factories were known as Dura Convertible Top.
-Dura apparently had a "North" and a "South" plant.
-When they originally acquired this prototype two piece hard top it was on a functional mock up with electrical actuators that allowed it to be demonstrated as a functional hard top.

Guessing here:
I suppose Collins and Aikman being the softop manufacturer for GM for the convertible Kappa's make this not quite a genuine GM part, but I would assume a prototype they had put together to pitch to GM as an aftermarket option, or possibly an official GM option had it not all gone belly up with the loss of Pontiac and Saturn.
One of the tings that makes this hard top unique is that it is the only one i have seen (outside of Nankoo's one off artistry ones) that allow you to open the trunk with the top still on.

I just closed the deal with the seller and do not have it yet however i wanted to post all the photos i have on it as of this moment.

Feel free to ruminate and speculate below.

Could you use it without the targa bar in the mean time, as a temporary solution?

It appears that your trunk lid is too high, as if it is not closed all of the way.

HH, sorry to see this doesn't fit perfect. Consider it a hiccup, and move forward. Is this something you can fix yourself?

I can but i had to remove the entire latch mechanism and chrome grommets on the trunk to be able to fasten the targa bar.
So i have two big holes in the trunk where the grommets were until i can put that all back.

If you look at the first pic i posted a close up of where the front of the targa bar meets the back of the top you can see that is precisely the issue.
I can close the trunk because the targa bar is hitting the top and preventing any further downward motion.
I can see any way to get the top lower as it sits on the weatherstripping on top of the rear quarter panel.
I may try removing the weather seal but that would lead to another set of issues and does not appear to get me enough height.
Too frustrated today, and will do a second round tomorrow.
Sigh

I was gonna say the same. It seems that if you close the deck lid fully the targa bar might align with the top..?
It looks as though the forward lower corner does not allow the the trunk to fully close. Is that the issue? Can the corner be radiused to allow it to lower down ? Otherwise it does look nice.

Good suggestion. I went back to Gadget's zoomed in "won't fit" photos and was cracking my head trying to understand what now (after your comment) became clearer to me and seems to be the junction of a kind of squared front edge of the T bar onto a rounded trailing edge of the top.

I wonder if the car Norm used as a base was "longer" than Gadget's by a few mm? Or Gadget's deck lid is a tad forward and could be adjusted at the hinges?

The solution to this is called Kappa Caps - DDM sells (had sold?) them. Attach them using 3m double sided tape...
Is it possible the trunk bar portion was meant to sit on weather stripping and thus be slightly higher on the trunk decklid? Maybe when norm was fixing and fabbing he might have made them level but the original design spec was for the trunk spoiler to be slightly shorter and sit on rubber like a tradition car rear spoiler does.........



example from my daily driver New OEM Rear Right Passenger Side Spoiler Pad For 11-15 Genesis Coupe 872582M001 | eBay this rubber pad sits between the spoiler and trunk giving it roughly a eight of an inch rise, it's likely the original design would've had something similar instead of having composite sitting directly on the paint, would that roughly give the clearance your missing?

edited #2 how certain are you the chrome scuff guards/circles are removed for installation? it almost looks like the spoiler section wants to sit higher and tilt forward instead of being flush with the rear deck..... wish I could be there to assist with this ;)

Wont fit with the chrome rounds on as the base of the targa bar sits on them half on half off..
Also the base is not flat on the bottom. (Will post pics later)
I had thought initially it would just go over the chrome circles but it does not.

knowing that the composite should not sit directly on the paint of the trunk i traced and cut a pattern of 1/16 rubber. I tried both with and without the rubber and it does not affect the geometry.

Yes i have a set and may do that, or i may just re-install the soft top and put the hard top in storage until i can figure it out.

Decklid is slightly “back” as is. It shuts correctly against the soft top and has a slightly larger bodel panel gap on the front edge than the sides.

This is likely the solution and was the conclusion i came to when i posted the photos.
it will be a real shame because it aint gonna be cheap and will require a repaint as well.

Thanks for the sentiment Chop. I am not a body guy and this one really needs somebdy very good. There is a mixture of bondo, steel and aluminum under the paint so it could get pretty tricky even for a savy body person.
One of the main reasons i asked Norm to do it was that i dont know a “good” body person out here let alone someone that can do custom work on this scale.
i guess i will start calling around. Sigh.

I would apprise Norm of the results, after spending a lot of time with the top he might know of some adjustment that is not immediately obvious.

He may also be able to explain how he test fitted it and what is different about what you are doing.

Some thoughts after a night of sleep.
The only geometry that makes sense to me would be to lower the tulip panel.
Because the current gap between the t bar and the top is a “V” where it is close on the outside edges and wider on the center top the place where the two pieces meet needs to come down. Since i cant lower the targa bar anymore as it already wont allow the trunk to close, that leaves lowering the rear side of the top.
- so big question is since the top sits on the tulip panel, is it possible to lower the tulip panel?

i doubt it but maybe someone here has experience with it. Is it actually adjustable?
And even if it is, i think that would misalign the interior plastic wouldn't it?

I will try to contact Norm of course.
its not that complicated though and i cant imagine i missed something. If you go back to photos i posted from Norm when he first got it and mocked it up, it had the same issue.
Except that the top had a squared corner to match the targa and now it is rounded there.
It also had a rubber gasket which it no longer does.

The squared of corner of the roof section in the earlier pics makes more sense. What is the purpose of the radiused tail on the roof section? Or am I not seeing the bigger picture because of the close up shot?
