Metal Work: How To Convert A 1960-1966 C10 To A Big Back Window


Metal Work: How To Convert A 1960-1966 C10 To A Big Back Window

When the C10 truck was first introduced for the 1960 model year, they were available with two different back windows. The small window came standard and was found in most trucks, so you can understand why a big back window truck has always brought more money on the open market. Because of this, there have been tons of trucks that were modified over the years to have a big back window and they were done in a variety of ways. The truth of the matter is that the back of the cab, on the exterior, is basically the same for either window option because the back panel has a flat recess that was filled completely by glass on the big window models and only had a small window opening in the middle of it on small window trucks. The difference lies within, where the interior panel is different from one to the other.

Thanks to modern replacement parts, you can now do a complete big window conversion with new parts. And not only that, but you can do it on a painted and finished truck if you are careful because the exterior of the truck needs part of the back cut out, but it doesn’t need anything replaced and that means no painting is needed. Now you will need to be careful with the welder to keep from messing up paint on the back of the cab, OR you can panel bond the whole thing and forget the welder! For those of you who don’t know, Panel Bond is glue that is used to hold body panels on cars and is used on new car construction from the factory. It is as strong, or stronger, than a weld and can be used in all kinds of sheet metal replacement projects.

Watch the video below to see how to use both Panel Bond and a welder to make this C10 into a big window truck.

    Great video showing the entire process. I do have a couple of comments on the cutting portion though as that still shot Chad used just scares the shit out of me especially when it comes to a DIY guy.

    Do a Google search “Cut off wheel emergency room” and click images. Yes, I represent a company that is one of the largest in the world in manufacturing everything abrasive and I take safety very seriously.

    While I have never had the pleasure of meeting Dave, I can tell he knows his trade and is extremely talented, no question. However, many like him use these tools in a less than safe manner which I see everyday in small, medium and large fab shops. Three issues just with the still shot: No Gloves, No Guard, and No Face Shield. If he were to hit one of the hidden supports while cutting, there is always a real chance the wheel can shatter as it’s just abrasive grain, held together with resin and HOPEFULLY a fiberglass reinforcement. It’s not designed to withstand a sudden stop especially from an electric grinder with plenty of torque and 11,000 rpm.

    Off my soapbox now! Great products from Brothers no doubt as I am a customer. Just be safe out there…you and your loved ones will appreciate that!

    I have a big back window 1965 and a standard window 1966. I personally prefer the standard back window. Keeps the sun off of you better and doesn’t block visibility like some think.

    I far prefer the look of the small window.

    Being a truck owner, the back of my neck prefers it too.
