I have a `54 Dodge Coronet Sierra 4dr Station Wagon....it's a 5" stretch...B-Watson, you're right on the money. 2dr Suburban wagons were sent to Mitchell-Bentley in Ionia, Michigan. The frame was baloney-cut and extended. The roof was extended above the front doors, the floor was extended in the backseat footwell. They used the 4dr Sedan front doors, custom rear doors, 2dr Plymouth quarters. This wagon is fairly scarce/rare: 1 of 1300 241 Hemi w/OD Any more info, pics of others, or for sale would be appreciated!
