Mugsy is right about the smaller diameter pipe, the ones I had on my Imapala were 1 7/8 OEM replacements I found at an old parts store in the mid 80's. They went out of business a couple years after that, sure wish I could have bought out some of their inventory! I used to get all the stuff for my old vehicles and equipment there. They even had the spark plugs for Dad's old Twin City sawmill engine on the shelf, I believe it was made in the early 20's. I know I kinda strayed from the subject there, just came to mind LOL.
