I am about to buy these two trucks but i cannot figure out wether they are 39s or 40s. I know that one is a GMC and one is a chevy but which is which? I dont have a in cab view of the yellow one just the green. There is a hood that is the same color as the green one and it says GMC but the color used is slightly brighter and is the standard color of most pickups anyway.

Picture 1

See the round speedometer (49 was first year)? and the black wheel (49)? but what about the beige nobs (40)? if it's a 40 the wheel should be beige to right?


Picture2

absence of bullet parking lights which is charectoristic of of 39...


Picture 3

2 piece windshield (39 and after)


So... what do yah think?
