difference in frames
 

Can anybody post pics of a 28/29 and a 30/31 front crossmember I know there is a difference and I'm trying to figure out which of several frames I have are which years.

The service bulletin shows the difference pretty well. If you look at the front crossmember the early frame is raised at the point the radiator attaches, the newer version it is recessed slightly. So if the mounting point is slightly higher than the crossmember it is a 28-29, if it drops below the crossmember it is 30-31. Hope that helps.

The picture with the fan shroud is my 1928 and you can see the radiator mounting pad sets higher than the 1930 frame pictured. The 1928-9 pad area comes straight out level with the bottom of the top frame rail. but you can see the 1930-1 pad area dips as soon as it leaves the frame rail.
