Have a really good looking later exhaust manifold but missing the intake. Can I use a earlier intake manifold if I don’t intend to have the manifold heater function?  I am sure I will only operate on gasoline. Thanks, Mike

Part # 2955-A (intake manifold assembly), Part # 2953-A (exhaust manifold assembly) and Part 2957-A (body assembly) are very different than the two earlier assemblies.

The change to the later style was at tractor #’s 4001A and PA 2528.

There is no easy, bolt- up interchange between the early styles (2) and the final assemblies listed above.

Anything can be made to fit with a good welder and tool and die maker.
