I highly suspect your rear end has been replaced with a newer model.
Highly unlikely. The rear brake cables and all the fittings on the frame, including the bellcrank is all intact and appears factory-original. This truck only has 37,XXX miles on it. The reason the brake lever is missing is because the truck sat so long that the transmission became rusted stuck. Someone before me took the tunnel cover off in an effort to investigate the problem. They had to remove the e-brake lever during that process and it was lost, apparently.
