Re: Hard vacuum line to the carb - questions.
Here are pictures of what's original to my '69 C20 with a 350 and no emissions other than a PCV. They show rubber at the ends and steel in between and no clamps. I believe the original rubber line to the vacuum advance was a bit shorter.I transferred the clip in the last picture from the original engine to my crate engine. It was attached to the hard line and the intake.
