    I don’t see where it identifies the applications for those manifolds??

    You can go to the Dorman website to get the info on application but it's not 100% clear. Amazon is notorious for not showing applications although you can enter your vehicle and it will say if it fits or not.

    Ok well I'm beginning to understand why the previous exhaust work tried to use washers welded on to the wrong flange. I cannot find a flange so far. 3 bolt setup and I'm measuring 3 11/16" center to center of the bolt holes. Which I calculate as close to a 2 1/8" radius for the center of the bolt holes. I stopped by an exhaust shop and a parts store and neither we're of much help.
    Anyone have any leads on a part number or where I can find a flange with these dimensions? Or an exhaust shop in Chicago that is worth going to for out of the ordinary work like this?

    That 'hole' looks to me like a pit caused by some wayward sand when the part was cast, rather than having been formed by rusting. If so, it shouldn't change or cause problems in the future.

    Is your flange largert than the ones used on 304 and 345 engines? If so, have someone look in a later Scout II parts book and find the IH part number, then do an internet search for it.
    Sellers of flanges for the above engines are discussed at the beginning of this thread.

    I know it may be tedious but trying going through the Walker catalog. I'm sure the part is out there. Remember all the International school buses that probably used the three bolt flange!

    Luckily my friend is going to fab something up but still curious for anyone else doing research if someone has a part number for a replacement 3 bolt flange.

    Thanks for all the help
