Every roof skin that I've melted the lead out of has had a weld - not spot weld - under the lead. The roof skin has been bead welded to the quarter skin (and probably whatever else is there also). But, cut it at the weld and it gets re-welded when it's replaced. 

That's too bad about the rust damage at the windshield. It looks like a nice skin otherwise.

Oh, and yes - the body lead is at that junction that shows on the hatch. With a little heat it will become evident. There's also lead on the A pillar in various places.

I asked a whole bunch of questions about type of weld in that same long thread.  Posts #102 and on are interesting.  Some thought spot weld some thought linear weld.  I think consensus was though that they were all ugly welds.  Also, some wondering, on my part, if it was welding or brazing.  I don't think that MIG was common back then.

I think that the end conclusion was that it's a complex joint.  I don't that there's a way to make a clean straight cut because there is overlapping metal.  You have to sacrifice one or the other side.

If it was brazed it might be debrazeable.  But you'd probably have to take a chance on destroying the base metal to find out.

I was at the local Z shop yesterday for something else and talked to the guy who basically was saying the same thing.  Because of the overlap you'd have to decide which piece you want to save unless you were able to undo the spot welds (if in fact they were spot welds).  I'll go read up on that other post.

This is where the roof overlaps the quarter panel. If I remember right, the roof skin has a flange at the back, so you'll likely want to cut a little below that joint. I've been trying to find pictures on google to refresh my memory on how it goes together, but not finding much.

Thank you for confirming what I thought to be the case.

Hihi.. just what i said, cut half way the a and c pillars..  (Under the complex joint.. so the roof is saved.)

Sorry, not sorry, this doesn't make any sense.

Both the roof skin AND quarter skin are very desirable pieces off a donor car. And you don't need to sacrifice one to get the other. "A" pillar, cut anywhere. "C" pillar, or whatever you want to call it, cut at the joint between the roof skin and the quarter skin! It's easiest if you melt the body lead out with a torch. Propane will do - it'll even melt with a heat gun. Then you can see the actual joint. When you have the skins separated it's easy to see how to transplant them to another Z. Unless one is trashed, save both. Just my 45 cents... (inflation)

I'm old. When I was a kid we could get 4 hamburgers for a dollar. Ever heard of "penny candy"? We used to buy it... Between then and now my "2 to 45 cents" is probably way wrong...😉

Yes, overhere we had liquorice, what we call "drop".. we had "drop" Cents, i remember we had 100 for 1 guilder so in dollar then it was about 275 "dropjes" for a US dollar i guess..

How can i make a Dutch guy crazy? Put him in a round room and tell him there is liquorice in the corner!

And a Belgian? ..  Say there are some french fries in the corner! 

The Dutch, we love our DROP!

$1.00 in 1925 is $18.23 today.

 

A US Penny in 1925 had the same buying power of $1.83 today. So your 2 cents worth is now 366 cents.

 

An ounce of God in 1925 was $20.67 - that is 31.1035 grams.(call it 31). $0.66 per gram.

 

An once of God today is $2,754.10 - that is $88.84 per gram.

 

133 times as much

 

Where did your purchasing power go?  $35,000,000,000,000.00 in National Debt.
