Back in the 70's-80's Mexico Build Chevy pickups used the current cab shell but the back glass was more like that of a small window '67 and the grill was similar looking but different from USA trucks. Bed was current but the tail lights were 1967 models, tail gates hook and chain and "CHEVROLET" font was unique. They were also badged as "DINA".
Now a days, I don't know about GMs there but Ford Super Duty F Series look the same as ours but use different components and powertrain options, For example they all don't have rear disk brakes and manual transmissions are still available.
