Chevrolet C10 Door Secrets - Open "C10-A" Me - Tech

The arm on the door lock is held with a special slide-on clip that uses a small folding tab to lock it into place.

To unfold the tab without damaging the special clip, I used a Craftsman jeweler's screwdriver to bend the tab flat. Note how I backed the special clip with a window-molding tool to hold it steady.

The best way to transfer the special clip to the new LMC Truck door lock is to place the old lock alongside and make sure they are positioned exactly the same.

The self-adjusting pliers worked incredibly well for sliding the special clip onto the new lock. Then the locking-tab was bent back into its hole with the Craftsman 3/32-inch pin punch.

Here's how the LMC Truck door lock looked after it was installed using the retaining clip LMC Truck supplies.

Thanks to LMC Truck's black inside door lock knob down to the brand-new show-chromed door handle and stainless steel shielded door locks, my '68 GMC not only looks a whole lot better, it's going to be a lot harder to break into.
