Next was the rear end ,lights differential and gas tank,all need to be correct 77..
OK the tail pannel was a challange ,i couldnt find anything that wasnt rusted to hell,and repro is out of the question,so i only found the upper section for the lights,and decided to take the plung and try a go at using the 80 tail pannel and fitting the 77 upper pan on it,,,,whats the worst that could happen i thought,i would just have to replace the who thing.
