I too am rodding a 37 truck. It also came from Minisota. Mine has a factory 9 foot box. I stubbed a 86 Dakota front end, boxed the frame, and used a 8 3/4 rear end out of a c body. I've got some extra parts that I'm not going to use. I've also repoduced the door hinge bolts if any body needs some let me know. Doing one of these old cars or trucks is a lot of work, but it's a lot of fun too! If you need any info email me at justnuts40@hotmail.com Good luck, Tony
