Okay that makes sense now
Yeah the 47-53 trucks didn’t do that kind of inside box detail
If you can’t get documentation here or online searches I suggest you find another truck to use as an example
Give Amigos a call in Calvet and ask them if they have one of those in stock to look at amigosauto.com
But keep in mind sometimes they have no idea at the front desk what old trucks are actually in the yard.
If you are close to them it’s worth the trip out there
