1963 UNIBODY? Mercury pick up truck...HELP!

Been looking at different classic trucks--1948-1970--to buy and/or restore and came across the 1963 Mercury pickup truck with a UNIBODY.  Can anyone explain exactly how these types of trucks differ from regular trucks,are parts more difficult to find for them,and  are they more difficult to work on?  I understand that Ford also had a UNIBODY pick up truck at one time--what year?

Where I could find some reading material or technical material on the UNIBODY pick up truck?  I have found several trucks that I am interested in but really would like to read up on these or discuss them first!

Thanks for your help!

Hi George,

First off is it a long bed, or a short bed? Being a Merc  brings up a red flag because they were Canadian, and unless it sat in BC barn for most of its life its going to have rust... maybe a lt of rust. The fast track on learning about your truck is to checkout www.fordtruk.com And of course jump back on here with any future questions you might have.  

It is a 1963 Long Bed, Mercury, Unibody.  One owner, and he has had it in a barn/shop and has done some restore on it.  I found some info regarding it being a Canadian sourced truck but very little to know information anywhere regarding the unibody design!  The truck is presently in Canada.  Don't know a whole lot more about it yet.  He is supposed to be sending me more info and pics.  Do you know anything about the Unibody design?  

Prone to rust is common. A shortbed brings more money than a long. Check out the website I told you about there's a lot about uni's on there, and a lot of really good guys that will answer specific questions. Also there's books with unibody info. Don't forget to inspect  for rust damage. Sometimes restored means packed with body filler.  

Unibody is Nothing new. Ford and Mercury are the same. Unibody was made in the early 60's both Ford and  Mercury. I don't remember how many years.
And as far as rust it depends what they use on the roads in the winter. Like MN uses salt ont roads Eat! Eat! And  next door Dakoda Don't and they have a lot of rust free cars.
