350 vs 450 dually bed differences?

[AirFishAutomotive]

is a 450 bed interchangeable with a 350 bed or is the 450 bed different in wheelbase. The 450 is an actual dually not a cab and chassis. Do not have both trucks here yet to compare and trying to get some things figured out.

Depends on the year.
If it is an 08+ then yes same. Prior to 08 the beds were the same but needed a spacer between the bed and the cab.

yes its a 6.4 08-10 dually f450, I know the older super duties were different we have been there and done that. But this is in regards to a 08 f450.
