Well:
Here are the pipes and as you can all now see the rear main and front chassis rail/ frame tubes are cactus.
Petrol cleans all the grease off them, but you have to be careful not to get it inside the tubes as it reacts with brake fluid... mind you the score is 1-3 with one pipe salvageable.
As you can see the rear main pipe was extremely pitted, and I managed to snap it on removal. It was good experience, as I was unsure if the pipes were pre-bent. It appears that by & large they are not except for a few tight radius's.
Having a 7/16 flare nut spanner will allow me to get the remaining unions undone. I feel like I am going backwards in destruct-a-tation, not forwards in
restoration.
Howard; Fancy a weekend at the beach??? Bring your pipe, swaging tools, tube & family..
