This picture is really concerning also if that area where the door hinges and lower door rail are is not perfectly straight your door will never line up and that’s super structural to the car and it’s kinda just missing not sure if it’s the picture but that’s a mess

Wayne, are you thinking you might have been a bit hasty in scrapping those cars?😉

I think I could have made a decent down payment on a Porsche or house if I would have saved those cars and sold them in today's market. But. it would have cost me how much ?? to shelter them from Mother Nature...

It’s possible but that’s going to be a ton of work I would almost just cut that entire part out and then graft on the donor.  Basically I would cut out the entire yellow area in my picture and then down far enough into the firewall and in straight lines to make welding in a new piece easier.  Are you good with a welder? 

Agreed. The other question is - do you create a fixture to mitigate any shifting. from the donor or the car to be fixed?

If I were going to repair this car, I would also replace all of the cowl. Probably all of the inner and outer cowl structure. I suspect the inner is very thin from rust and the outer is basically gone.

Is this area an anomaly or is there extensive rust in the rest of the car?

I too scrapped out a few cars that I regret not saving. The rear view mirror is 20/20 as they say. Now I keep everything I can.

I saved this off a 70 shell I picked up a while ago, as it was in too good of shape to scrap. I cut the firewall below the spot weld line. Most of the A pillars are there too. The bottom was toast. 

Getting it to FL might be a challenge, but if you were interested........

Wow... i to have scrapped a 240z that was better then that!!  It was a car with a original Dutch license number so it was all it's life here in NL.. But those are often also the bad ones because of the weather.. 

How is it possible that a Z has such a bad cowl?  was it near the titanic?? (as wal280z sayd..) or in the rain? (In Tampa florida???? it's not a Florida car then..)

I would like to see the rest of that Z-car? Pics?  They must be of a very good car otherwise it's not worth the work you will have to correct this mess..
