I have a '69 f250 that a previous owner put a 460 in. Not sure what year 460, but a starter from a '70 lincoln is the one that fit. (The local advanced auto has an old guy who used to be a dealer parts manager. He plugged in cars with 460s till we found a starter to match.) I need to replace the exhaust, do any of you guys know if the y-pipe from a late 70s F-series that came with a 460 will work in the 69? Can't easily run duals because the fuel tank under the bed on the drivers side pretty much fills the space between the frame and drive shaft.
