I am installing a fourlink rearend on a 53 chevy pickup half ton frame. There are two holes at the top of the rear of the frame. I need to know which one is the rear bed bolt hole. My measurement to put the new fourlink crossmember in comes off the rear bed bolt hole. My 53 now sits on a wagoneer frame, so I can't use it to check which hole is the correct one. Thanks!
