I have a bad floor/back panel/toe boards (accident/heavy rust)
my upper is very good.

I have located a 58 cab with a bad inner roof, very solid bottom half. http://www.thehollisterroadcompany.com/media/cab/58/

My photos are in Tuesday link

QUESTION: How diffucult is the inner roof to replace? This is my first major sheet metal repair

Thanks
Brad
