I love to top. Some say I top too much., current topic: sourcing targa top seal track Options

[ahycaramba]

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.

How much heat and cold transmits through the roof top? I was contemplating using Noico 150 mil insulation padding under the headliner material.

How much heat and cold transmits through the roof top? I was contemplating using Noico 150 mil insulation padding under the headliner material.

I was running just a bare shell in the GT replica. but was noticing much heat transfer in hot CA sun. Given that most of the miles in are on the road, not the track, I decided to add some insulation.

I ordered a headliner piece from 914rubber, but prior to gluing it in, put in a layer of Dynaliner (.25" thick), which is a closed cell foam heat insulation product. It comes with a self adhesive backing and can be cut to shape easily. Worked a treat and hides under the factory looking living material nicely.

No data on surface temp differential numbers to hand, but a few times this summer the temp difference between inside and outside targa temps was easily felt. FYI,

PS. Was interested to learn on this thread that the early/late tops are tied into the early/late doors & window winders. Think I may have the wrong top type on now (which may explain the generous window gaps...!)

Thanks Tony for answering to my question about insulation to the top. I'll definatly follow suite. I'll be running without ac and heat for a while so I have to do everything I can to make it as comfortable as possible.
