55-59 cabs are identical, except the 58 cab has slightly different hood mounting

the mount holes on the 55 hinges can be modified a bit to work, but expect some struggling to fit the hood
mount points [4] should be obvious - front= pass right foot, drivers left foot, back ones about 8-12" from rear of cab outside of frame - steering column has to be removed and stowed b4 liftoff
