If you post a pic here I would be happy to tell you if it looks like my 28...
Also a few measurements. What did you want for it? I know another guy with a 28 in boxes.
Be careful with what size is correct. Like the ad Norm sent there are several for the 1928 model year. I know my Model 65 radiator is about 2" longer than the regular M-! or M4 model. Found that out the hard way. I now have both and when you put them side by side, you can tell the big difference.
Where Are You From? Oviedo, Florida
Do You own a car built by Durant? Yes 1928 Durant Model 65 4 door sedan
My shell is also 29" by 20" and it looks like My Durant M2's Shell. Pretty much identical if you look at the above picture. So I am guessing this should fit all 1928 Durant M2's. I wouldn't mind having an extra but I Can't afford it at the moment.
I can see about the guy with the Durant in the box.
