I’m restoring my 79 Plymouth and found most of the old vacuum hoses are either missing or broken, I’ve scoured the internet to the best of my ability but can’t find any info. does anyone know the sizes of the hoses used in this diagram?
You got a pick a part or u pull junkyard near you? Just go around and grab whatever looks right. Get a couple different sizes just in case. They probably won't even charge you.
