found my dad a project...how rare is it?

[67cst]

hey guys, im new over here on the 73-87 board so i just want to say hello! i found my dad a truck here in my town and was curious as to how many were made. its a 1980 chevy short fleet cheyenne 2wd. it has been lowered a bit and all the trim has been removed and painted black. being a cheyenne its too bad it was dicked with but still its a great truck. it has a 350/th350 combo, with ac, tilt, NO buckets unfortuantely, posi rear, power windows and locks, ummm other then that im not sure, we are 67-72 guru's so we have lots to learn about the newer trucks. does anyone know how many cheyennes GM made in '80? also dont shoot me but ill get pics posted asap.

thanks, Derek
