new to the c10 world!
 

hello everyone,

i have a c10 here i got for penny's! I've never done one of these trucks before its a leaf spring truck. i bought a trailing arm frame to swap over and build while the cab and bed are out at paint. i guess my question for you guys is there a way to identify what frame year my extra frame is? the numbers are 72 J163161 is this a 72 frame? all info is appreciated thanks guys!
