“what’s the difference between a 1977 blazer and a k5 conversion like this?”
A stock 1977 K5 Blazer and this pickup conversion are the same truck at heart, but the body changes make them look and function quite differently:
Body style
Dimensions
Drivetrain & chassis
Market positioning
Bottom line: you gain pickup-bed utility and a unique square-body look, but lose the enclosed SUV cargo area. Collectibility is slightly narrower (custom vs. stock), yet the workmanship and modern upgrades keep resale strong—about on par with a really nice original K5.
Want to see other K5s or square-body pickups? I can pull up more listings or market data—just let me know!
