Hi World - I could use some verification of assumptions:

I'm planning to build a permanent roof that, at least as it's designed now (!), will use a steel "frame" structure, approximately like the 916, with a carbon skin bonded to that.

This will be done on a late ('75) chassis with a set of early ('72) doors.

My current assumptions are that there are no "early vs late" issues I need to worry about in terms of sealing around the top, front and rear of the door windows. I know there are early/late differences in the actual door-related seals.

ASSUMPTION: So long as I replicate a place for the targa top-to-window seal to attach, I should be set to go, yes?

Confirmation or correction appreciated. Thanks in advance.
Chris

And as I start on this roof, pics will be added as part of my build thread:

I'm afraid not. Early doors won't seal correctly against a late top and vice versa.

Ask me how i know ...

Andy - Thanks for the reminder. I had seen that thread and that's why my question. I'm making the top so what I'm trying to understand is if there's any difference in any of the "top of the window to roof" seals.
I can fab the seal "holder" part of the top to put that seal wherever it needs to be.

Or am I missing something else? Sorry to be so dense...

Yes, the later seals have an extra lip that helps with sealing the top of the glass but i never got them to work correctly on my early doors.


PS: I should probably add that i have a late top with late seals and early doors.
