What do I have?

Ok, I bought this truck an have been working in it. Rewired it and put the glass in it. Title states it's a 1960. But I want to start working on the front suspension, new spindles, disk brakes ect... I needed to replace a few wheel studs so went to the local auto parts store and asked for 1960 C10 wheel studs (I was kind of smart and brought the ones I pulled off) they didn't match. After digging around the parts store the studs I brought with me matched a 1963 C10 stud. So how do I figure out what front suspension I have??? If the wheel studs front and rear have studs for a 63 is it safe to say that someone swapped the suspension from a 63 onto this truck? Or did they just cut off the torsion bars add airbags?
