Power window conversion

[ssman9]

First off I have been a member for a little while and have been collecting information for the rebuilding my 1977 Big 10. I bought this as somebody's forgotten project and have been gathering up parts and ideas from here until I get started on it. Don't worry I'll take plenty of pics and I'm sure I'll have more questions.

Now on to my question. I would like to convert to power windows and locks. I have searched but couldn't find an answer. Does it matter if I use a kit out of 81 and newer truck versus one from an 80 an older? I know the door panels are different and I have to rewire my truck anyways so that's not a problem either. I was just wondering if the inside of the doors had any changes throughout the year. Thanks, Mike.
