Keith:
My Prefix VIN for my 77 Sport is: CCL447. My questions applies to the
4th diget. (4) which is the Series. GM book does not give info on what
the "4" means. It gives 1 = 10 2 = 20 3 = 30 Series. Would 4 perhaps
apply to shortbed series or maybe big 10 H/D chassis?? Thanks in advance.

From what I remember the 4 indicates 1/2 ton with heavy duty suspension.....they may have put the change in the vin to establish a different emission control package.
Your SPID should show hd springs or suspension;also your gvw rating.

OK Keith ...am I on the right track?

according to my GM parts books a "4" is 10 series with RPO F44, pickup models only.
F44 is Chassis, heavy duty

OK; that confirms it; H/D chassis. I assume nowhere in the VIN
differentiates a shortbed from a regular bed. Correct?
Thanks to all. Larry

Correct. That's encoded in the model number (ie, "CC10703").

Here's a link to a VIN decoder, for your future reference:
