Got a small new project completed today - seat belt holder-uppers! My wife will greatly appreciate this one - it always took about 5 minutes of fumbling for passengers to fasten their seat belts.
Anyway - I started by ordering 2 Ford "Buckle Sleeve - Black 12"" from LMC Truck for $13.90 plus $8.75 shipping. These are Part No. 48-2334-BL. Then I set them on my bench for 3 months. This is an important part of the process.
Finally I got motivated, and trimmed the tops to clear the upper half of the buckle assembly, and shortened the tubes, and cut a notch so that the installation would force the belt to stand up straight between my Corvette C-4 seats and the center console.
PS> The last picture is added as a special bonus for two of my friends. They will recognize the connection! Thanks to you both for your hospitality!
