30-31 model a cowl question

GOT It APART, THANKS, I am putting together a tudor sedan that needs a fire wall and have its gas tank replaced: i have a complete four door cowl that i would like to take the fire wall and tank from: how do these come apart? i see a few screws, are there any spot welds? when i got the sedan it was already chopped: so if i use the 4 door cowl i will have to chop it: any thoughts? sk
