Installing Mar-K’s Body-Side Molding on a ’77 C10!
Nothing sets off an early squarebody more than a complete set of body-side moldings. A few different manufacturers make this molding, and we have used them all. However, we have found that the molding made by Mar-K is of the best quality, resulting in the best overall fit and finish. Although offered in individual pieces, we opted to get the complete upper and lower sets with clips. Mar-K moldings are made from thicker-gauge US aluminum. Finished off with black or 1977 only gold accent stripes and are then bright anodized for protection and a shiny finish.
We are building a ’77 C10, but we decided on the black accents as it fits with the build a little better. If your truck had this molding from the factory, the installation is relatively straightforward, but the install process can be a bit daunting if it did not.
Our truck was an original Silverado with factory trim; however, we replaced several panels, and the only place the original holes remained were the cab corners. Mar-K offers a couple of options for attaching the moldings. One option is to use clips with an adhesive backing. Another option is to use a combination of clips that consist of metal clips with studs and nuts and the aforementioned adhesive clips. Both include screws that are used for attachment. We used the combo kit as we felt it would provide a more robust installation.
With our truck, we were in the final mockup stages before paint. This is a perfect time to do the installation and drill all the necessary holes.
This can also be done on a painted truck, but you must use extra caution and use lots of masking tape. Make sure to measure twice and drill once. Also, it is crucial to make sure all of the bodylines are aligned correctly. If not, it may be time to replace the cab bushings. It is best to have a friend to assist in the installation process. We asked our dad to help; there is nothing better than a shop project where you can spend quality time with your dad!
