Broadcast sheet from Galen Govier?

Not trying to hijack the thread here...but I have completely ripped my 72 duster apart for restore and I have not found a single build sheet.

How would I go about getting one and is there even a way to do so?....I see some of you have mentioned there being no record for early 70's and I see some of you have mentioned contacting them and recieving the computer tab in the mail but you mentioned nothing of cost so was it free? and I also see some of you mention sending $45.00

I guess I am jsut a little confused here....any clarity on the subject would be great,thanks
