Tim,
Those bed sides are 47-53 sides. They have the correct number of bed stakes and the angled top. The latch is likely a farmer add on. It looks like a fencing latch. Be aware of what year the bed front panel and rear sill are. In mid ‘51, if I remember correctly, they changed the number of bed boards from 9 to 8.
