Hi everyone. I'd like to put lap belts in my stock 1950 3100 and am seeking recommendations. Ideally they would look like they belong in there even when at rest when unused. I don't need anything fancy or colored (basic black is perfect). Also, I'm seeking easy to install as I cringe at drilling any holes in the truck (at least any more than I must). Thanks in advance for the insight.
