John Deere A air stack replacement

[Problems]

I'm just about done restoring my 1940 John Deere model A and the air stack is rotted out. I cut it off and prepped the casting for a new stack, but the new stack I got doesn't seem to fit right. As shown in the picture the bump for the steering wheel is moved up about 3/4 inches. Therefore when the top of the new stack is level with the exhaust stack, the steering wheel shaft will not go through the intake stacks bumpout. I got the part from stiener and they said they are all like that. So I guess I just need to cut the bottom of my brand new stack about 3/4 so that the steering wheel shaft will be able to go through. But then the stack will sit about 3/4 lower. Are there any other options? I would think they would have made the reproduction stacks the same as the origional

I have not personally used one of those aftermarket air stacks, but I seen those sort of things alot over the years. Why go to all the trouble of making a part and just a wee bit more effort it could of been correct ?

Ehh, looks about the same, who'll know.

I would send it back to Steiner and order another one from a different supplier like right here on YT.

Scroll down a little on the attached.

Do you have the correct exhaust stack? Not all mufflers are the same height either.

If nothing else works, saw a little off the bottom. Nobody will notice

Don't cut. Send back to Steiners; tell them they have a problem where they are locating the steering shaft indent; it is in the wrong place!! Try another supplier..
