If been these for yours, just about got motor finished ready for stout body swap on straight axle frame. Biggest down fall no windshield. Debating making convertible or modified similar windshield, maybe old chevy windshield cut down will get close
Even though they're rare, I like the idea of giving it your own personal touch. If you want convertible style, consider a removable hardtop instead to keep the character. Convertible trucks usually look kinda shit, even when done well. You could also create interchangable windshields, if you were so inclined. But whatever, it's your vehicle, and you should do what you want to do with it, rare or not.
Probably cut back of cab out and put bench in back seat with full roll cage. Don't know if you guys know Pepe but like is truck
