OK, I am finally taking out my truck project that has been sitting in my garage for a year. It is a small window cab F100 and I want to know if there is a way to make it into a big window cab. The guy I bought it from gave me extra roof with back window part of cab. I have found a Ch**y site that shows out to make the replacement, but nothing for Ford. Can it be done??? or do I just stick with my small window cab? I hope this made sense. Thanks for any info.
