All the Model A Ford Roadsters and Coupes I've had or sean had rumble seats, I want to convert my '30 to a trunk. I bought what I was told was an original lower inner panel, but I don't see how it would line up with any factory holes in the quarters or rear sub rail crossmember. Are the 28-29 and 30-31's different? A photo of a 30-31 sure would help. Thanks and Merry Christmas!
