Perhaps slow to the party.. Mac's

[Savvy]

So, I've been purchasing parts over the years from Mac's.
Invoice's come back "Mac's"
Today I called regarding an interior question for '34 Ford Fordor Dlx......
Didn't get Mac's, so hung up and called again.
Surprise surprise, right number, unexpected answering remark "Eckler's"
How long has this been?

And my question....
Are the headliner measurements linear or do they include the length of the front and rear curves?

Cheers!
