need to know the model of this truck

[marcele]

Hi everybody,

I am 3D modeling a frame truck but I haven't found any info about the model on it.
I have been looking on the internet and the dimensions and shape are very similar to the 1973 - 1980 Chevy / GMC pickup truck frame on this link:

But I'm still not sure if it is one of this or not.

I'm attaching some photos below.

Thank you in advance
