Minor correction.
It isn't a "C20"
It is a 1500 series (assuming it is, in fact, a 3/4 ton)
C20 would make it a Chevy.
1/2 ton - C10 - 1000
3/4 ton - C20 - 1500
1 ton - C30 - 2500
Otherwise...
Welcome to the group. One thing you will come to understand (and possibly hate) is that the parts stores either think GMC and Chevrolet use the same parts, or they will argue that a 305 is a v8, not a v6 (or my favorite "they didn't make a v6 in 1960,61,62,63,64,65,etc")
Motors manuals, if you can find them, are reasonably accurate with data. Chiltons (who now owns Motors) is decent as well.
Factory Manual will be X-6523 if you go looking for one.
What is most annoying with parts is that it can be the one part you are sure wouldn't be different... that is different. For instance on my 1963 2500 I had to replace the rear wheel brake cylinders. Those couldn't be different, right? Chevrolet lists the same part both sides, GMC has a right and a left and it does matter since the brake line won't line up with where it connects to the cylinder if you use the Chevrolet one (I do not remember which side that was).
Wiring harnesses are different, components under the hood are different... you will find all kinds of parts that don't cross over. It makes it more "fun" to work on!!
At least your '65 is in one piece. Mine is in several pieces (as in previous owner completely disassembled it... if it could be taken apart, they did. Even the leaf springs were taken apart)
Have fun with the truck though. They are solid, dependable, and reasonably easy to work on. Once running at its best, these are difficult to kill.
