Need help with VIN

[Yukon Bronco]

VIN on frame...U15NEC59011

The C could be a G

 

[okie4570]

68' wagon with 289 built in 12/67'. The E is an L, and if that C were G it couldn't be an N there for a 289. G in the C location would make it a 70' and broncos didn't have 289 in 70', just 302 for the v8 option.
