Need help on locating exhaust manifold for a Massey Ferguson 200 crawler with a perkins ad3.152. I know that the massey ferguson part number is 1 434 862 M2. I need a newer part number or a perkins part number to a comparible manifold. The one listed is a massey ferguson design and is no longer available, don't need one with the rear facing port, as it is just covered with a plate and screws. Any help is greatly appreciated. Thank You.
