Fred, What is the difference with the later 29 style? I'm just asking because I just bought a 28-29 radiator for my 29 sport coupe. It hasn't arrived yet and I didn't know there was a difference so I didn't ask any questions. Thanks, Matt.
There were several, but the most noticeable is the channel in the back of the top tank put in it for clearance of the shell rivets. This started in June of 29.. I have a picture of one if you need it along with the other style..
