I know there is a difference in tops from early to late. My questions can the tops be interchangeable if the internal latches and fasteners are swapped? is it only the latches that make them different or is the structural also different?

Thanks in advance.

I'm curious myself as I've never researched it. And I need to figure out someday which of a couple of tops I have around here are early or late. So this was timely. (IMG:style_emoticons/default/popcorn[1].gif)

Early top has a thin rib, late top has a thick one.

So what is the time line that delineates between early and late? (IMG:style_emoticons/default/confused24.gif)

If I'm right about the side windows being different, it would start when the newer style window mechanism was added to the doors. Mid '72 I believe.

@Gint
@mepstein

I have a late top that I am going to add the early rubber blocks to
and test fit on an early car.
The early blocks are shorter and wider. I don't know why they would change that.
I don't know it the top web height was changed at the same time.The window seals should not be an issue. 914 rubber list the late seal as better sealing and can be used on the early car for better sealing.

Then I am going to test an early top with late blocks on a late car.

Will report back her with the findings.

The other top differences do not appear to affect fit like the raised bosses on the front latches.

I have a lot of recent experience with this.

The top must be matched to the type of window regulator. If you have early regulators, you have to have an early top. If you have late regulators, you have to have a late top. It has to do with the seals and how they meet up to the top edge of the windows.

I know this for fact. My red six conversion (Igor) is a 73, and the top (painted to match the car) is an early top. So the seals don't fit right, and they leak. The top on the Blue 70 914-6 (Elwood) is a late top on an early car. The seals don't quite reach the top edge of the windows. So I added an aluminum strip between the top and the seal mounting track. They actually touch the windows now, but they don't fit right either.

I actually took the top of the red car and put it on the blue one. The seals fit fine when I do that, but the car looks really funny... (IMG:style_emoticons/default/biggrin.gif)

I have a early top that I am going to get refinished like they did at the factory for the blue six.

Also, a 70 914 didn't have a headliner on the underside of the top.

@altitude411 Thanks for finding Paul's posts.

And I now realize that the top on my 74 is an early top. The late top was sitting on top of my /6. It looks pretty nice and only needs a couple of tiny paint applications. And a left rear mount.

@ahycaramba Did this discussion give you the info you were looking for? Questions?



@bdstone914 Hey Bruce,
Do you have a late left rear targa top mount? This part. Or a set refinished would be great.

I did find another targa latch mount, albeit a crusty one with crusty hardware. That late top on a late car makes a lot of difference. I don't have any idea why I did that or when. Probably because of a mount failure (or departure).

I don't know about you but I hate when water leaks inside the car. Thanks to all who have tackled this thread. Your help was VERY useful and informative. You all saved me from making a mistake and future headaches. I can't thank you enough. (IMG:style_emoticons/default/beerchug.gif)
Hope to meet up with you guys one day and thank you in person.

Interesting thread, I've been trying to find a really good 'stock' top to be able to swap out my body colored top just to change up the look if so inclined. I have 3 spare tops now as I've searched for one that needs only paint and minor refinishing vs a full on re-do.

After this thread, realized that I have two early and one late, I need the late one so will be probably bringing the early ones to sell off next time we ever have a G&R Swap meet...

As long as we're on the subject...

What is the preferred product to treat a top exterior to freshen it? Even further, if a guy wanted to respray it, what's the DIY solution or product?

Here’s how, and the product I used. It turned out nice. Distance when spraying the texture coat, will give you the factory effect as far as texture. Then finish with the black satin used in an earlier post on the same page for the bumpers.
