C10 Trim Installation

Installing trim on your Chevrolet C10 can be stressful! The thought of drilling holes in my C10 gave me major anxiety especially because of the lack of guidance and directions available. That's why I created this simple guide to installing your custom cab trim on your 1962-1966 Chevrolet C10! Watch the video below, then follow the directions to easily install trim on your C10!

Instructions: 

Watch the video above to have a complete understanding of the instructions below. The video will answer many of the questions you may have and go into detail about measurements and techniques to use to ensure correct installation. The trim template print off is not complete yet but the instructions below, in addition to the video, should give you all you need for now!

To install our trim, we are simply making a couple measurements across the body and pulling two pieces of string to align those marks. After the string is in position, we will measure and mark where each hole will be drilled.

1. Start by placing 6 inch strips of tape vertically across the truck. 8 pieces of tape should be plenty but place as much as you like. We will use this tape to measure and make marks across the body to confirm our string measurements. If you feel more comfortable taping up the whole area where trim is installed to keep from scratching your paint, then this is totally fine!
2. Staring at the rear of your bed, measure and mark your tape at 2 3/16 and bottom mark at 4 11/16. Continue to measure and make these two marks across all pieces of vertical tape. (The fender measurements are hard to measure so we will use our string to help determine the fender measurements.)
3. After your tape is marked, tape a long piece of string across the top measurement at the rear of the bed. Tie the end in a knot to keep it from sliding out. Pull the string tight until you align it will all the marks.
4. As you pull the string, align it with the marks on the door and tape it onto the fender. This technique will help you determine where the string should go on the fender since it doesn't have a great body line to measure from. (see video again if confused on this step)
5. Tape a string on the bottom measurement and align it with all the lower marks to the edge of the front fender.
6. Once both strings are aligned and taped correctly, begin to measure each panel and marking your holes. I like to start at the front fender and make my way to the back but each panel can be done in any order. Each panel has a specific point to begin your measuring from.
7. Fender Measurements: Place your tape measure between the door and fender and begin your measurements there. This is the measuring sequence: 3, 13, 23, 33, 43, 48
8. Door Top Measurements: Place your tape measure between the cab corner and door. This is the measuring sequence: 2, 9.5, 17, 24.5, 32, 39
9. Door Bottom Measurements: 2, 9, 16, 23 (then use your trim to determine vertical hole mounting position)
10. Cab Corner Measurements: Place tape between door and cab corner. This is the measuring sequence: 1, 2.5
11. Bed Top and Bottom Measurements: Place your tape measure on the front of the bed and measure toward the back. This is the measuring sequence: 2, 9.5, 17, 24.5, 32, 39.5, 47, 54.5, 62, 69.5, 77
12. Remove all your strings and tape and prepare to drill your holes. I went through and used a punch on each hole to keep my bit from moving. I started out by drilling a small pilot hole then moved up to the correct size bit.
13. The upper trim hole will be drilled with a 1/4 bit.
14. The lower trim hole will be drilled with a 7/32 bit.
15. You can use a piece of vacuum hose or an ear plug on the bottom of your drill bit to keep the drill from hitting the truck as it drills the hole. This takes a steady hand and a clear mind! I'm a praying man so each hold had a quick prayer lol. 
16. After all holes are drilled, you can use a q tip or touch up pen to slightly cover the bare metal spots in each hole. In the video my truck was getting ready to go to paint so I skipped this step. 
17. Install the clips into your trim and pop in or bolt in each piece starting with the front. Some installation clips may be tight. I found that removing the felt and sliding the clip in was easier. I would place the felt back after the clip was installed.
