I'm new to antiques. Have a 56 f-350 express. Need to replace cross sill rear on the 9' bed. Will a f-250 fit. As I can't find one any where

 

Welcome to FTZ. I believe the F-250 would have had an 8 ft bed and your F- 350 a 9 ft. Your question needs some clarity. Are you talking about the sill itself or putting a F-250 bed on the truck?? Not sure about your description of "express"??

Only need the cross sill rear.

 

Express, 8 or 9 foot boxes are wider than the 6 1/2. Your box has small wheel arches inside. You may have to "stretch" the standard, short box part.

 

Thank you. Good idea, or machine shop

 

Thank you good idea, also a fabricator

Thank you
