1931 ccpu on 1929 chassis

Yes. It will require some creative shimming to get everything in line but it will work.

Unless it's a late 1929 frame the radiator will sit to high because of the
different front cross member.

Here is one that I did. The cab is december 1930. the running gear is november 1928 . We shimmed the cab. It didn't take a whole lot but it was enough that I had to use longer bolts from the local hardware store. I had to elongate the holes in the front cross member to align the 31 radiator. We used a new repro bed, back fenders, splash aprons and running boards. All and all it worked out fairly good.

forgive my ignorance, but what is the difference? is there a stamping (part number) on the member that can identify them?
 
On the 28-29 chassis, the front cross member has raised bosses where the short radiator mounts; the 30-31 chassis front cross member do not have the bosses where the tall radiator mounts.

If you try to use a 28-29 chassis for a 30-31 it is not advisable as the body, when properly shimmed, will set high above the frame.

If you have a 28-29 frame I would suggest you replace the front cross member with a 30-31 front cross member.

Ron, truth be known, its not that difficult and looks perfectly normal when its done on A pick up. I have been told by a reliable source that it is more difficult with a car body. I posted pictures of the one that I did above.
