'29 Rumble to Trunk

[bputhuff]

I have a '29 Coupe with a rumble seat that I want to convert to a trunk.

Is it true that I can just flip the lid around, or is there a different curvature to the rumble vs. trunk.

Another point of confusion is that the latch end of the rumble lid also has what appear to be provisions to mount the trunk hinge pins. I also see matching holes in the upper gutters.

Finally, is the sheet metal floor of the rumble compartment different in the trunk model?

Thanks for your help.
