32 pick up bed dimensions?

[ratamahata]

Hello guys I'm planning to build my own bed for my roadster 32 cowl, I knows the 32 roadster are very rare and have a differences with the roadster coupe cowl, my cowl It's belong to a phaeton car cut... It's any difference with the roadster coupe and the roadster pick up in terms of sub rails, please anyone would bring me the dimensions for a 32 pick up bed, I understand that's the passenger car and the pick up chassis are the same, only don't know if the chassis rails in the rear are flat or have a slow down form like the chassis car, Wouldn't find a pics of a bed mounting....
I've recollected a few pics for the web and The Hamb threads, but no have any results at this moment!!

Thank's Leandro
