Re: 1965 Seat Belts???
Well today I remembered to go out and take a couple pictures of the B pillars in my '66's. My '66 C20 has the 'nuts' on the backside of the holes. However my '66 C30 has the holes with no threads. My C20 was built in the Fremont plant and my C30 was built in the St Louis plant. I also discovered that you can tell what is in the hole by the look of the plug in it. The ones that have threads, the center depression in the plug is only about 1/4". The plugs that are plugging just a hole in the sheetmetal have about a 7/16-1/2" depression.
